Wait... don't go saying stuff is "debunked rumors" when later Compilation entries elaborate that they really are true... That kinda negates the point of the thread...
-All members of SOLDIER have Jenova cells (this was due to a line of dialogue in the original game that explicitly says this /rolleyes)
"All members of SOLDIER have Jenova cells" is confirmed as true in other places in the Compilation. Especially in the Ultimanias and CC.
Ultimania Omega Keywords (2005)
from The product of the project: Sephiroth
mass production of SOLDIERs required adults of sound mind and body who could be injected with Jenova's cells and exposed to mako,
from Jenova Relation 3: The Sephiroth Clones
The experiment's procedure -- which involved injecting cells taken from the headless body of Jenova into the subjects and exposing them to mako -- doesn't differ from the manufacturing procedure for SOLDIERs. The largest difference is that SOLDIERs are selected from a prime field, being strong of mind and body and able to withstand the experiment uninfluenced by Jenova's cells, whereas the Clones' fragile minds leave them as "portions" of Jenova.
from Successful work, failure work
As for the mentally and physically strong, carrying Jenova's cells inside their bodies will not cause them to receive Jenova's influence, and they will not become a puppet of Jenova like the Sephiroth Clones, but will instead become a SOLDIER possessing strength far beyond that of a normal human being.
from Lifestream Relation 3: SOLDIER
Shin-Ra's elite soldiers. The Turks scout to gather those who would be capable of handling being injected with Jenova's cells and exposed to mako

from SOLDIER
The private army of the Shin-Ra Company, bestowed with great power through being injected with Jenova’s cells and showered with mako.
FFVII 10th Anniversary Ultimania Keywords (2007)
from SOLDIER
「 FFVII – BC – CC – LO 」
Those who are injected with Jenova cells, and are exposed to high concentrations of mako to be made into the ShinRa Company’s enhanced soldiers.
Crisis Core: FFVII – The Complete Guide Keywords Collection (2007)
Jenova Cells
The cells from Jenova used in the Jenova Project and SOLDIER surgical procedures. Those who have been injected with these cells undergo physiological changes such as improvement of their physical abilities and partially receiving Jenova’s abilities. However, mentally weak people are unable to withstand Jenova’s will, and it sometimes brings about mental abnormalities.
from SOLDIER Degradation
A symptom of a particular flaw inherit within the G-Series SOLDIERs and their copies. It is due to an imperfect integration of Jenova cells into their bodies, and the symptoms worsen as their genetic information is spread to other beings.
And finally, from the orriginal game which is what all the above entries are based on...

You see, someone in SOLDIER isn't simply exposed to Mako energy.
Their bodies are actually injected with Jenova cells......
If they *really* had wanted to change SOLDIER having both Jenova Cells and mako in the Compilation they could have, and they didn't. Instead, they doubled down on it repeatedly.
Related to that last point: Sephiroth was the first SOLDIER (I’m pretty sure this one was only debunked like two months ago)
The OG itself suggests this isn't the case. DoC flat out confirms that there were SOLDIERs in Midgar (specificly in what would become Deepground) before Sephiroth was born.
Ultimania Omega Keywords (2005)
from The Shin-Ra Company
Originally a weapons development company named “Shin-Ra Works,” it grew rapidly from the discovery of mako energy. Deploying crystallized mako energy (“materia”) and elite troops who had been directly exposed to mako energy (“SOLDIER”) to the battlefield, Shin-Ra guided to its end a great war that had engulfed the whole world in those days
This suggests that Shin-ra first came up with SOLDIER back in the days when it had first discovered mako... that is... back in the late 1950s or early 1960s. A full seventeen years before even Jenova was discovered, let along Sephiroth had been born.

Deepground
A creation of President Shinra, its very existence is hidden in the dark. Originally a medical facility for SOLDIER, following the existence of the SOLDIER called “G,” all ethics were disregarded and the purpose of the facility was perverted … as all work now went into producing the most powerful of warriors.
FFVII 10th Anniversary Ultimania Keywords (2007)
Deepground (DG)
「 DC 」
A top secret ShinRa experimental test facility built deep under Midgar. Only very few members of ShinRa know of its existence. Originally a SOLDIER medical facility, as time passed it was transformed into an extralegal research organization which, disregarding all logic, strove to determine how strong a person could become. Once a unit called the Restrictors kept DG under rigid control, but the DG SOLDIERs orchestrated a rebellion, with the strongest Tsviet Weiss at the heart of it. They eliminated the Restrictors, and were freed from their control.
These entries show SOLDIER existed before Genesis was created, as Deepground already existed as a medical facility for SOLDIER at that time.
And here's the OG showing that Vincent apperently knows what is meant by this term (and who it's affiliated with) right when he wakes up...
Vincent
I was with... the Shinra Manufacturing Department in Administrative Research, otherwise known as--the Turks...
Vincent.
Cloud
The Turks!?
Vincent
Formerly of the Turks.
I have no affiliation with Shinra now.
...And you?
Cloud
Cloud, formerly of SOLDIER.
Vincent
You were also with Shinra...? Then do you know Lucrecia?
Cloud
Who?
Incidently, the Twilight Mexican wrote this articale:
Was Sephiroth the First SOLDIER? that goes into *way* more detail than I do here... There's still a lot of ambiguity for *when* exactly SOLDIER was created, but there is some very good evdience for it being around in some form much earlier than Sephiroth being born. Even if the exactly nature of it wasn't quite the same as "modern" SOLDIERs due to Jenova not being discovered yet.
And of course, now we have The 1st SOLDIER game that proves that no, Sephiroth was *not* the first SOLDIER...
