But it's been an uphill battle because XOrg is the final boss of legacy codebases.

Also because Wayland forces every compositor to be an unmodifiable monolith instead of following the UNIX philosophy. For example I'm currently running i3 inside of Xfce because the de, wm, compositor, and every other part are doing their own thing and can be replaced. With Wayland I'd need to fork the compositor and spend a ridiculous amount of time on something that's trivial in xorg.

And let's not forget the garbage pile of tools that got abandoned a week after release because Wayland introduces breaking changes on a regular basis. You want unified shortcuts across multiple compositors like with sxhkd? Tough luck, the only tool was abandoned after the first version and doesn't work anymore. On the other side you've got 15 rofi alternatives you need to dig through to find out which ones are still maintained and might work on your device.

On top of that Nvidia GPUs have so many issues, and while that's not solvable by Wayland, it's still a major issue that still hasn't been fixed after 15 years, but might maybe soon™.

Finally, the security improvements have gave me nothing but headaches whenever I tried using Wayland. No matter the distro or compositor, screen sharing and recording never worked for me. Give permissions, share whole screen or just window, it's either black or the program is not showing I'm trying to share ate all.

You can't blame it all on xorg when Wayland is still simply far worse for a large part of the community.
