To add to this, I'll post this here. I was going to post this in the X-Men thread but since this is about Spider-Man 4 putting it here is easier. I wouldn't be surprised if they shoved Jean Grey into this film somehow. Every MCU Spider-Man film has had a marvel character in it that didn't really need to be there lol.
Spider-Man Homecoming: Iron Man
Spider-Man Far From Home: Nick Fury
Spider-Man No Way Home: Doctor Strange
Not to say their inclusions were forced or anything, but for each of those stories they could've used actual Spider-Man related characters. Especially in No Way Home, Madame Web could've had that role and the movie wouldn't have changed much if at all. Though because they were making that spin off movie it couldn't happen. I also don't think she's playing MJ because well, we have an MJ. That wouldn't make any sense especially because they already confirmed Zendaya is going to be in the film so. Idk. I'm so curious how this movie is going to turn out lol
