I guess the only thing I worry about (as unlikely as it'll be) is that in an attempt to appeal to "both sides", they'll sneak in little references that her chest is even bigger than it appears because of the sports bra. Something like Yuffie walking in while she changes and exclaiming "Wow, how do you even walk with those???"
I just straight-up don't want her chest to be an in-joke, because a big part of the fandom already did that to a ludicrous degree, which is why I also winced whenever Square would nudge them along with cheeky references like this:
In Final Fantasy XIV, there is also a Tifa minion you can purchase, which is adorable and does a punch animation. The description calls it "a gravity-defying rendition of the famous brawler" and I can't help but think that's another boob joke.
It's honestly nitpicking and not a big deal in hindsight. The only reason I prefer they don't do this is because it's just adding fuel to an already smoldering fire caused by the online fandom. Ultimately, they were a major factor into why Tifa's design needed a revision in the first place.
