Xlibre (the only current actively developed implementation of a X11 server) has a new extension - XNamespace to address some challenges as well.

Not the only one, there's also a new one (written in zig) I've forgot the name of.

edit: phoenix was the name: https://github.com/external-mirrors/phoenix#phoenix

Hard for me to take that one seriously.. For example they call out byte swapping for endianness as the type of cruft holding back X11. Such a trivial thing to be concerned enough to put in the readme... (I guess Phoenix is also putting this..) Seems like mostly authored by Claude too.
