In those cases the adapters are chosen solely on the specificity of the
adaptation's requirement and it becomes easy to mix up semantics from
I'd be interested in a use case where adapting to Interface is not just a
(questionable) convenient short-cut but an actual semantically correct
operation and could not be replaced with a more specific interface.
Looking at zope.component.interfaces I find that there is an inconsistency in
the APIs. The actual registry APIs all require an interface to be specified
for an adaptation, but the module-global facade API provides
zope.interface.Interface as the default. I take that as another indicator for

I don't think zope.component wants to know about views. The interface should
be in a package that already knows about views.
