Here's a dumb question:

How much of this work is transferable to Wayland?

Afai understand it the kernel work is transferable the x work isn't. What i still haven't understood is how much work has been done in wayland in order to support all the funky features multiple inputs outputs graphic cards multi whatever.

Other than the kernel stuff, most of the work is windowing system specific so it needs to be implemented separately in each windowing systems (windows, macos, X, wayland, etc.). As such there is very little code at that level that can be shared which is probably why you see no support in the nvidia driver. You can't really share anything with the windows driver. Additionally, it requires certain shared infrastructure which makes it hard to mix open and closed drivers.
