In principle that’s ok. But for 5.6, our focus should be to have things
working with Cocoa. This is the 99.5% use case, xcb is a fringe platform
on the Mac.

So for 5.6, I agree with Morten that cocoa vs xcb sounds like a configure
choice rather than something we do dynamically. For 5.7, we could get
things working from one build if someone is willing to do the work
