Now that we apply the callback with the correct generic signature, the assert can go away. It was being triggered if the protocol extension was defined in a different resilience domain; otherwise we prefer direct access anyway. Note that materializeForSet now has to be able to re-abstract Self when invoking the callback, since we might have to go from a thin metatype to a thick metatype.
