Warframe is unplayable without this fix, so I'd say getting this into mainline Wine would definitely be a good thing.
I wouldn't mind if the patch accepted, but please note that it is more a workaround instead of a proper fix. As I explained in https://www.winehq.org/pipermail/wine-patches/2016-July/152110.html:
