XWayland is still supported, and afaik will be for some time. It's only standalone Xorg which isn't.

Thanks, this might be what I'm looking for. It's covered here: https://wayland.freedesktop.org/docs/html/ch05.html and https://www.mankier.com/1/Xwayland

Ariadne Conill is turning Xwayland into a full X11 replacement: https://github.com/kaniini/wayback. She doesn't want to maintain it long-term, so if you're interested in contributing, please do: the more people understand the codebase, the better.
