NVidia user here, it most certainly is not working well. My external monitor for my laptop is getting black boxes shadowing the kde menu and most of my windows on that screen, and often block boxes trailing the mouse.
There is a strong desire to see if there is secret sauce in the driver that makes their cards so darn performant. Could it be applied to other video drivers?
To audit for vulnerabilities and fix them.
To allow the driver to use some kernel internals that the kernel developers keep trying to wall proprietary drivers off from.

Community might be able to hack it to work better with Wayland, since the Wayland team has no interest in extending any kind of support to proprietary driver driving GPU’s… despite x11 working just fine forever. … see Ideology.
Dual monitor? Wayland on my intel works fine for single screen, but as soon as I plug in a 4k monitor, it gets black cube shadow like artifacts in KDE Plasma 5. A couple of kernel command line options for the module has not helped, either.
Waypipe is not Wayland. Wayland does not natively support this workflow, which is why Waypipe was created. Please don’t confuse the two as being one thing.
