It was always an option, but "just" needed someone to dedicate all their time to it and pull in a group of long term maintainers. The real question is what will happen with the project in 2 years and will it be stable for day to day use.

The fact that you can "assume Vulkan exists" helps a lot (both hardware and software renderers exist). Do remember--Wayland predates Vulkan by almost a full decade.

In addition, you can offload OpenGL compatibility to Zink (again leaning into Vulkan).

"Use new cool language" seems to be a prerequisite for this nowadays ...

At least Zig is very compatible with C.
