You know you can run XWayland and have clients connect via network?
There’s still some development going on in Xorg and it’s pretty much all XWayland, it’s going to stay alive as a compatibility layer for the forseeable future and beyond. And as a network layer until someone thinks of something better (no, sending video isn’t better, the strength of X as a network protocol is that it doesn’t need much bandwidth). It’s the hardware interface stuff, actually throwing pixels on screen, that’s thoroughly dead.
