Not that I actually have the time to work on this, but I'd been
thinking about xkbcommon lately. Do you think it's possible to build a
compatibility layer around the current code? Either the compat code
could live in the server or it could be an optional extra library
shipped in xkbcommon. I'm not sure if the changes in xkbcommon are too
deep to be able to build a keymap for current XKB or not. What do you
think? It seems silly not to be making use of xkbcommon in X.
