This is primarily for registration convenience. It allows us to reuse mechanism.

Technically, an interface is a utility that provides IInterface, however,
I agree that the focus is much different.  The fact that we can treat an
interface as utility for registration is only a convenience.  When we talk
about Zope 3 development, we won't talk about interfaces being utilities.

There will be an interface-centric UI within the site-management UI for
browsing interfaces and viewing and browsiing the system configuration by
interface.
