Yes, I see your point. Two questions:

1. Are chained inclusions of modules a good way to propagate class
methods? (Do we really need this feature, for good design?)

2. Do we really want the modules to respond to the class methods that
they provide to classes? (I think that's the way your class_extension
works, but in my own test implementation I avoided that.)
