This is a current feature of zope.interface.  Therefore, zope.interface
requires it, unless you can show an implementation of this API which does
not depend on it.

It is certainly true that this API could be removed from zope.interface.
At that time, zope.interface would not depend on these frame APIs.  It
would also break almost every user of zope.interface and require them to
change to the new API.

Don't try to mix "could work" with "does work" together.
