Okay, reuse of directive definitions and implementations is more
widespread than I thought initially. Which is silly of me, as Grok
itself also reuses directive actions (but not definitions) in some
places.

As far as I understand in a recent discussion people indicated they
didn't like deprecation warnings anywhere, as they are forced on third
party users of code that itself isn't deprecating anything. Since
Christian's tool is as I take it well underway couldn't we just rely
on this? Also since it actually *fixes* the state of a ZODB, instead
of just giving a lot of warnings and then leaving the helpless
developer with writing some scary custom upgrade code.
