Sorry, my sentence came across wrong! I definitely did not mean that the ZCA should make it so by default, I meant that in my particular application I would like it to be that way without necessarily having to add a classProvides statement to each derived class.

I understood that, I just phrased my question poorly. So given the clarification, is there a straightforward way for me to make it so, or will I need to make a metaclass that enforces my desired behaviour? thanks!
