Nvidia is just really really bad on Linux in general, so it's always a coin toss if you'll be able to boot your system after messing with their drivers, regardless of display server.

For most purposes, including gaming, it is best to avoid Nvidia hardware. Using Intel for laptops and AMD for dedicated GPUs is kinda the best general approach if you are planning on using Linux.

Of course if you have a need for CUDA then Nvidia is the only game in town, but that is a different issue then Wayland support.

For a while Nvidia was fighting the Xorg/Wayland devs over GBM vs EGLStreams which has delayed Wayland support. This has to do with the API extensions that allowed Wayland to manage application output buffers.

Gnome was the only Wayland environment to try to support EGLStreams for Nvidia, but it really didn't do them any good.

A while ago Nvidia eventually switched over to GBM and EGLStreams is dead, which helped out a lot of people running non-Gnome Wayland desktops. But there are lots of problems with Nvidia drivers besides that right now.

The reality is that Nvidia doesn't care about consumer Linux desktop. Their primary focus is on Enterprise users in terms of people needing graphically accelerated desktops.

So right now if you are running Linux on your personal workstations/desktops/laptops you are essentially beta testers for whenever Enterprise Linux distros make the switch to Wayland.
