Hello David, sorry for the delay.

Well, you can try this, but whether it has a chance to work at all depends on quite a few factors: whether the API or ABI have changed at all in the meantime, whether all libraries/programs that have a DT_NEEDED entry for libxcb-xlib.so.X also have DT_NEEDED entries for the libraries where the required symbols are in now, *and* their sonames have not changed, or at least something further up in the dependency tree loads the required code; whether symbol versioning has been used and if yes, whether the requires symbol versions all still exist; then it could also depend upon whether the Xorg people have not played games with -Bsymbolic. If I were to try it, then yes, making libxcb-xlib.so a symlink to a versioned dummy library libxcb-xlib.so.X (don't forget -Wl,-soname!) sounds like a good approach to me. Hope that helps.
