“Even though Wayland has existed since ~2008 as a replacement for X11, it’s only recently that some Linux distributions have been enabling it by default.”
Wayland is 14 years old and Blender is only now supporting it natively, in 3.4. The developers looked at SDL and decided they’d have to become SDL developers to make tablets and 3D mice work. That’s the Linux desktop in one paragraph. Every app has to rebuild its own plumbing before the “replacement” replaces anything.
