As far as I can tell, enabling the trusted/untrusted security feature breaks a lot of basic features, including clipboards, XRandR, GPU acceleration, XKB keyboard layouts, and whatnot. It's theoretically available but practically useless.

Xnamespaces looks to be more promising, but as far as I can tell that's still a WIP with little documentation, and from the documentation I can find it looks like it still breaks things like clipboard functionality.

Well, the threat is shared access to resources like clipboards, so securing against this of course breaks the clipboard. Pick your poison.

Permission system? X11 with a permission system is the next logical step for Unix graphics. There is absolutely no need to break 40 years of graphic software, or throw away 40 years of accumulated features.

		Yes, but even a permission system can only give a program access to the clipboard or not. You can't deny a program access to the clipboard and complain that the clipboard doesn't work.
