I don't think that this is an accurate description of current situation. If testers who install F25 get wayland by default, all this tells us that it mostly works, but not that it's ready for widespread use. There's still a long list of open issues until feature parity with X11. Those things don't get reported as bugs, because they are well known missing features, not really bugs, but they cannot be ignored. I've been using gnome-wayland myself for the last year, and I think it's great, but there's still too many shortcomings. IMO, the only reasonable course of action at this point is to make X11 the default for F25 and punt wayland on to F26.
