I don't think I would like to redesign my objects just because the
addIntIdSubscriber does not catch NotYet when getting IKeyReference:

@adapter(ILocation, IObjectAddedEvent)
def addIntIdSubscriber(ob, event):
    # ...
    utilities = tuple(getAllUtilitiesRegisteredFor(IIntIds))
    if utilities: # assert that there are any utilites
        key = IKeyReference(ob, None) # HERE IS RAISED EXCEPTION
        # ...

Is there a way to override .addIntIdSubscriber in overrides.zcml or another way?
I would write my own version which is more forgiving and does not allow to go
out NotYet raised in IKeyReference adapter.
