Thanks.

Yeah, you're right, it would be cleaner if that were split out as a
separate package (or moved to xkbcommon).  This workaround is ok for
now, assuming most people still have X11 installed in parallel, but for
folks wanting to run pure-Wayland setups if they want compose keys too,
having the compose config data only available via libX11 will be a
little awkward.
