I don't like the use of devmode for that, especially as I hardly ever 
use devmode for anything (Grok doesn't really do much with it as far as 
I know).

I prefer a tool that's external to the source code in question. You 
could base it off something like that importchecker (see pypi) does. 
It'd analyze what imports take place and whether it's importing from a 
place that marks itself as deprecated.

Your mention of the ZODB issue brings up a good point. We'd also need a 
ZODB-level tool that can do this reporting in this case. The current 
deprecation system already covers this case, though, right? Besides an 
import checker you'd need a system that would be able to thrawl through 
a ZODB and report deprecated classes. The drawback is that it'd need to 
thrawl through a ZODB, so that's rather costly. The benefit is also that 
it'd be thorough and find all instances, not just those that happen to 
be in use by a particular application.
