My only concern is that XCB based Xlib might not be considered as stable
as old Xlib and distributions don't want to include both an old Xlib
library and a new XCB based Xlib library.

Whether, the XCB library itself is currently included or not shouldn't
matter much. If it's not included, that's probably because not enough
applications use it and making compiz require it is probably enough
reason for them to include it.
