FWIW, I'm also in the camp of thinking it is not worth the effort.  Until there is a demonstrated need (something than can't be met by checking for __set__), the default position should be to stick with a core usable set of ABCs that are know to have real value.  Each new ABC has a non-trivial maintenance burden and requires extra effort on the part of users to learn and remember.
