If the future MCAS 2.0 runs only one time per flight -and less excessive- afterwards pilots have to fly "MCAS unprotected" in manual flight with flaps up conditions.
So all MAX pilots have to learn flying with no MCAS close to a stall anyway. Why is MCAS still required for certification? Obviously without MCAS a MAX is safe to fly as well if that system will be switched off after one use per flight. (I am aware of the stick feel close to a stall requirement)
