I've tried to document the differences, which should be minimal for
folks trying to port apps (I think the differences are mostly
cosmetic). Of course, there are probably some I missed :)

Definitely. I'm happy to consider any incompatibility between the two
a bug, and work on or with someone to fix it.

Yes, the primary purpose for writing it was to provide a better
experience for users of Qtile, a window manager I maintain written in
python. We finished porting Qtile to xcffib several months ago, and
our first xcffib-based release will be in a few days. As long as Qtile
is around, xcffib will be too :)

Sounds good; I usually spend 5-10 hours on Qtile/X related things, and
I would be happy to at least accept patches, and potentially build
some new code if it would be useful for others.
