I don't think the movie-verse is ready to go that way in canon. The only thing a canon Sharon will do to the stonyshippers is give them someone to bash because she's so mean to Steve (absolutely unrelated to whether she is portrayed that way or not in movie canon). It's not as if Pepper stopped them. Shippers gonna ship regardless of canon.

Personal opinion only, I've just always found Steve/Sharon a bit of a creepy idea. I can kind of gloss over it in the comics. The movie did a really good job with making Peggy real and a part of the story though and now I just find the idea of Sharon being directly blood related even more of an ick factor. Feels too much like dating the daughter because you can't have the mom. I'm hoping the franchise can pull it off somehow so it feels normal but, wistfully dreaming, I'd rather they hadn't tried at all.
