One difference with the DB-API is that DB exceptions are intended to be seen by the user, to be caught and reported in application code. The case we're discussing here is where a hook wants to report an unusual, but normal, condition (that the backend discovers *at runtime* that it can't do what has been requested of it) and the error is to be handled by "the other end of the protocol" (the front end) and is not for reporting to the user (except in the limited sense that we're considering whether the return value/exception needs to carry "why this failed" information that the frontend can report to the user if it wishes to).
