Wayland seems ready to me but the main problem that many programs are not configured / compiled to support it. Why is that? I know it's not easy as "Wayland support? Yes" (but in many cases adding a flag is enough but maybe it's not a perfect support). What am I missing? Even Blender says if it fails to use Wayland it will use X11.
When Wayland is detected, it is the preferred system, otherwise X11 will be used
Also XWayland has many limitations as X11 does.
Wayland isn't even adopted by every desktop environment yet. xfce, cinnamon, mate, lxqt, and all the ancient window managers all use x11, and all have their users.
If it works on xwayland, chances are it won't be switched for a long time.
