No one wants to. Wayland is the successor to X11, X devs now work on Wayland. Gnome has first party support for Wayland because the same devs also work on Gnome and Red hat.

The inconvenient truth is they are working towards a cohesive desktop experience, even supporting mobile. X11 will still be here, but you can't blame the devs for wanting to move on.

Operating systems should be designed for all humans, not just programmers. Gnome seems to be the only DE that cares about accessibility. All of your settings and extensions mean nothing to someone who needs all of their apps to work with a screen reader.

This article and these comments suck. No one wants to contribute code, just opinions. Reminds me of the systemd FUD.

You can fork, hack, make your case with Wayland, maybe it gets merged, maybe you just maintain your own fork. These criticisms by people who aren't going to contribute anyway are getting tired.
