The reason we put it in there is for implementors to be able to offer extensions more easily. Of course we could use unwrap to do as you said but it seems to me that would undermine the UX to please frameworks wrapping BV calls. note that they could use a dynamic proxy instead of a static delegator pattern to be API change proof.
