No crew should have ever taken the airplane there.
No crew should ever take the airplane to a point where MCAS is required, either.
If MCAS activates without being in that region, however, it is controllable, it is stoppable, and the aircraft is flyable.
It may be the difference between who occupies the front office: a pilot or a passenger.
Airplanes that lose engines are also flyable. I wouldn't recommend designing one that fails the engine when the flaps retract with an AOA probe failure.
