I agree. If we go this route, we should delay a release of
zope.component 4.0 for a significant period so we don't get code
depending on it. That may be quite a bit longer than 6 months.
I'd be nice if we could express dependencies like: "zope.component >
3.11 or zope.component > 4.0" but I don't think that's supported yet.
