Hiding the interface declaration in some exotic place in ZCML isn't very
helpful IMO. We can add a comment to the implements directive in both
classes that these are not implementing the full interface, though. Five
isn't just an add-on anymore but a core part of Zope2, moving things
into the proper places, should make it easier for those people, who
haven't followed the whole history of Five.

All sounds fine as next steps, hopefully someone is willing to put some
work into it. My main motivation besides making things more easily
discoverable was speed increase. For some reason five:implements or
classImplements is the slowest of all CA actions, when combined with
complex classes. Moving these two statements to the classes themselves,
made them take just the 75th fraction of time then before.
