Congrats for founding that.
Well, IMHO, even if XCB had a XKB support, it would not solve the
problem. Xlib, in a lot of place, is doing magic stuff to ease
programmers life but it's not a raw access to the protocol like XCB.
We can still do like Xlib and convert XKB event to MappingNotify in
xcb-event for example, but since no one is supposed to use this lib if
they do not want to, they are screwed.
The good work-around is to have a XKB support in XCB and le the
application select the corresponding XKB-mapping-notify-event and deal
