Don't mind me, I'm just a big FF7 thinker and here are my latest thoughts. I don't mean to write so much, it just happens!
In short, the two main interpretations on Remake's ending are that Zack's scenes take place 1) in the past or 2) in an alternate reality. I'm in the latter camp. Below is a breakdown on why I don't think the past was changed.
Some of these I've posted before. Until a theory comes around that addresses all of them, I'll remain unconvinced.
1. Stamp's new design is spotlighted by the camera. If the past was altered, then showing Zack’s survival would've been enough to communicate that. Why present a new design for Stamp as well? Furthermore, the design is not shown to have been affected by the defeat of the Whispers. This suggests to me that Stamp is not an additional alteration, but rather a label of distinction (between Zack’s universe and the party's).
2. The story would have a very different starting point if Zack survived in the past. Consider all the character development that would be affected. Not just the interactions the party had with supporting characters, but also the supporting characters themselves, such as Jessie, Leslie, and Rufus. Consider Yuffie’s DLC story, which takes place before the Whispers' defeat, but released after Remake. All of this would be changed. Altering the past is narratively destructive because it separates the player from the story told so far. (Tommy 86 on Discord made this point, I’m just hijacking it)
3. The Whispers intervene to prevent major deviations from the original game's story. If Zack survived in an altered past, but events still led to the party meeting up and escaping Midgar, then why were the Whispers monitoring him at all? To have events play out similarly regardless of the Whispers' influence reduces their purpose and threat throughout the narrative.
4. Zack's survival scene in the ending is inserted between scenes of Shinra and the Sector 7 slums, both of which follow up on the story as it was told in Remake. It's not separated from the rest of the pack or given a visual effect to hint that it takes place in the past. Instead, it's presented straight and even features a new design for Stamp to boot. I'd argue that from this cinematic perspective, Zack's survival is shown to happen at the same time as everything else.
5. If the defeat of the Whispers altered the past, then why was Zack's survival the only thing that changed? Why weren't other events, such as the Whispers healing Barret's stab wound, changed as well? This issue is avoided if you view Zack’s survival as taking place in another universe. All of the Whispers’ influence on the party's past is retained, but their future is now free, as are other universes where the events of the original game have yet to transpire.
