What's the state of wayland support?

I want to install Sway but apparently Nvidia doesn’t support wayland yet. What’s the roadmap? Thanks.

It seems that the problem lies in GBM API support. Also, I heard that there was an attempt to develop the next generation of API (https://github.com/cubanismo/allocator), but there is no activity in the repo for 2.5 years.

So I came here to get information about current progress towards Wayland support for Linux. Any updates?
