We hope to deprecate zope.app.catalog entirely eventually, so we should 
support people as much as possible in moving over to zope.catalog. Just 
removing the ZMI stuff is a relatively straightforward deprecation step. 
Removing configuration essential to the functioning of many applications 
is less so, which is why I'm saying it's not bad we do this in two steps.

Ah, yeah, that would make documenting things easier too: just include 
zope/catalog/subscribers.zcml if you them.
