This is hitting on a fundamental issue - Wayland's technical merits are not important. In the early phase I personally think its adoption was crippled early on by the poorly designed screenshot support. Particularly as the computing world turned out to need good video support for 2019-2022 we were lucky to have dodged Wayland. These days that seems to be less of a factor, I gather that a new parallel system of standards have sprung up that technically haven't replaced Wayland but ... for all practical purposes everyone will need to implement the screen-sharing aspects of that world. The parts are slowly being put into place. But final adoption depends precisely on what the distro maintainers think is a good idea with a little dash of whether it is technically possible for Wayland to work. We put up with X, so Wayland has a low bar to clear technically.
