I have nvidia and use wayland. It works just fine. I think you are referring to a nested caveat of this which is that the subset of applications still coded soleley against the X protocol will run without gpu acceleration under nvidia and Xwayland. The number of these apps has dwindled thanks to gtk and qt moving over to wayland, now chrome and firefox have early wayland support, and like you said nvidia will soon support Xwayland.
