Gripes are unconstructive, though. I'm just as disenchanted as the next person, but in the FOSS world the ethos is rightly, put up or shut up.

Personally, I suspect that if the Wayland developers simply dropped maintenance of Xorg completely--no more patches, no more XWayland or at least completely disassociate XWayland from Xorg--that a community would step up and carry Xorg forward. As it is, that erstwhile community remains largely hidden, maintaining out-of-tree patches. But if that community faced the prospect of 1) being able to take back the reigns of Xorg, and 2) if not, Xorg vanishes today, then it would likely become much more motivated, organized, and proactive. (Whether it would be capable of carrying Xorg forward is a different question.) Alternatively, it might create the environment for projects like Arcan to shine.
