Except, Lic, that depending on the choices you make over the course of the series, it's possible that you would only get the friendship version of the Highwind scene and thus, no romantic angle at all between him and Tifa. What I see is something of how the OG didn't enforce a canon pairing but basically let the player decide and interpret for themselves. And there's no reason that Part 1 can't do that as well while still including Jessie as a third option. The point is to allow the player (and thus, Cloud) to have the choice while it's still available to them, and to give them more than they were able to have in the OG. Just because he could be with Tifa at the end of the series doesn't mean that he couldn't ever have felt anything for anyone else before that. People are capable of caring in that way more than once over the course of their lives. Cloud doesn't have to be any different.
And apple, just because she's only in Part 1 doesn't mean she shouldn't be given that opportunity of being a third option for Cloud while she still can be. It's something that can affect the part of his story that happens in Part 1. His interactions with her before you even really meet the other girls (saving her twice in the reactor, potentially flirting with her on the train, etc.) are actually the first sign that he's not the selfish guy that he tries to pretend he is. So it's not so unreasonable to think that, depending on the choices the player makes, she could play a part in thawing him out just as Aerith does, since he's sure to develop friendships with her, Biggs, and Wedge by the time of the plate collapse and thus, their loss will hit him harder than in the OG and he'll likely feel it as much as Barret and Tifa. And so, apple, that means that she can have an impact on FF7R, at least Part 1.
Also, SE's deliberately put Jessie in at least one new situation that's very likely to feed her feelings about him - riding with him through a harrowing bike chase and clinging to him is bound to have that effect on her. SE could have easily created the scenes and minigame with Biggs behind him instead of Jessie, but they deliberately chose to put her with Cloud and not only that, show multiple closeups of the two of them instead of keeping the camera zoomed out on all four the whole time. They didn't have to do it that way, but they chose to. They could have also had Cloud find the Restore materia himself like in the OG, but they chose to have Jessie give it to him instead.
And it's possible they they've made his saving of her in the reactor something more dramatic than just pulling out a stuck leg. We haven't seen that yet, so there's no way to know, but it is possible. And when she's in the parachute with Biggs, after she looks away from him (she never does look him in the eye, only sideways to listen to what he's saying, and a bit abruptly at that, as if she was startled to hear him talk - notice how quickly her head moves up, like she was lost in thought), the camera shifts to bring Cloud into view, and if you follow Jessie's line of sight at that moment, you'll see she's looking right at him. SE doesn't seem to be hiding her attraction to him, and if they weren't going to do anything with it, you'd think they wouldn't have deliberately increased it the way they already have or put her in situations that would fuel it even further.
Having Jessie as a third option for Part 1 (remember, that's optional, just like the way the OG did it - it all would depend on the choices you make through the game) wouldn't hurt anything and would give her the chance to potentially have something she was denied before. It would also give those who don't care as much for Aerith and Tifa a third option for Cloud so that they wouldn't be forced into choosing between two options they may not like. Me, I like all three girls, I just want the underappreciated one to be given her chance in the sun with Cloud for once now that she has this opportunity, one that doesn't come along that often and one that she won't have again after this game.
