It's not just the meta.zcml story, where I can agree we could leave
something in place, but it's the dependencies in setup.py, right?
If the implementation of the directives lives in zope.componentzcml, any
codebase that loads any ZCML at all (in its tests especially) is very
likely to need zope.componentzcml besides zope.component. Or am I
missing something here?

If my above story about the dependencies is right, it is necessary to
remark this in a central place. We do have framework-wide policies in
place, and explaining to people how to unbreak their code in a single
place they can look should be one of them. We do after all have people
who use a whole bunch of these libraries at the same time. But if you
can write it clearly in the CHANGES.txt and tell me, I'll add it to that
document if you can't be bothered.
