You're against a docstring talking about zope.component overriding 
these? Seriously? I mean, just mentioning zope.component in the 
docstring is taboo?

Now as to the default behavior of these methods:

Basically the default behavior of the methods would be like nothing ever 
got registered. That looks reasonable to me, +1.

Okay, I guess that does make sense.
