Both of you are right :)

ZCML lets you defined abstract features, e.g.:

   <meta:provides feature="devmode" />

You can then check for such a feature using zcml:condition:

   <foo zcml:condition="have devmode" />

I think it would indeed be nice to reuse this, especially since we're 
not using the ZCML machinery for grokkers underneath anyway.
