I don't want an X server that supports Wayland. I want a leaner, simpler X server without Wayland.

EDIT: To clarify, the reason I mentioned Wayland compositors is that it'd be an opportunity to pick a low-level rendering backend that has been written from scratch without the baggage of Xorg.

The "good parts" of X that modern apps actually use are comparatively simple compared to the low level bits - the protocol is trivial-ish, and you can get 90% there by implementing a small-ish subset of the protocol.

XWayland can be run in 'rootless' and 'rootful' modes.

Rootless is what it is typically ran as and allows you to integrate X11 apps into your Wayland desktop environment.

Rootful would allow you to run X11 desktop with X11 Window manager and the whole ten yards.

I don't know how well rootful mode is working because it is rarely used. I imagine it would take some work to make it fully functional. But it something that exists and I would expect that the Xorg/Wayland devs would like to see it fully fleshed out.

But that essentially gets you most of the way there.

But then I'd get the baggage of both a whole Wayland compositor and much of Xorg. I want neither.
