Well, not 100% useless: I can see its use for applications running inside Docker containers. Yes, there are ways to have GUI applications rendered from the inside of a container, but maybe this is easier than getting the Dockerfile right.
EDIT: nevermind, doing this with Docker seems much easier than I expected [0]. I'll try it tomorrow, I'm curious to see if the proposed solution works on Windows as well.

Windows had Wayland support before most distros! Rather surprising.
