If you believe that the '(IAnnotation, None)' registration is not
supposed to be a view, then the correct place to address this is in
'zope.annotation', not the publisher. E.g.:, the attached patch.
Note that the two-argument registration was added by Jacob Holm in r72995
(2007-03-05). CC'ing him to ask if he can recall the justification, or
knows what would break if we removed it. At a guess, the motivator is
zope.app.preference, which wnats the extra argument passed to its
__new__: this is *not* a reason to reguster a multi-adapter.
