Yeah, so is not shitty for those claimed X11 devs to drop X11 since is hard and make a spreadsheet with a specification of a subset of X11 , then let other suckers implement it and maybe some other suckers create specifications of the missifng part they refused or were incapable to create. Probably all was exactly as Red Hat planned, if it works for GNOME then the rest is ignored or if it does not work for the rest then is a bonus.
