X.org picked the right level of abstraction (even if implementation could use a rewrite). No WM should care about handling raw inputs or forced to be proxy between driver and the app for the output (it could be, if it needed/wanted, but there is no reason to add another layer of abstraction and cycle-wasting for most use cases). And it shows in complexity and even in power use. Wayland basically failed to learn the lessons from X11
