Actually I'd say it's not typically hidden away. It's signaled by a
directive (grok.grokked(), say), *or* by the base class being used in
the first place. There are also frequently other directives that can
Compare with ZCML, where there is truly no information in the code that
this code will be registered by some file somewhere, perhaps even 10
packages away. If you are in favor of conventions, why are you not
suggesting we prefix ZCML registered classes with a Z, say? :)
