I would rate the most likely case would be an aircraft upset followed by an nose-low recovery at a speed approaching Va (max maneuvering). Not sure how often this sort of thing has happened in the real world, but the FAR certification requirement that drove the need for MCAS cannot be waived because the possibility of such an event is deemed unlikely.
