I suggest that this *is* explicit.

If I have:

   class Foo:
       implements(IFoo)

you are very explicitly saying what the class implements.

The proposed change is to not consider base classes.
Ultimately, this makes the algorithm simpler from a code
inspection point of view.

It is a pain to have to *repeat* that information in the
registration.  I have found this to significantly reduce the
burden of ZCML.
