Until a point is reached where multiple AoA vane failures can be dealt with safety, accounting for MCAS, it’s not an airworthy design IMHO.

Large multiple bird strikes to the radome can cause issues to airflow which make AoA readings erroneous. It was a known issue on a previous fleet. You simply need to be able to turn off MCAS or have an override switch that takes tabular data of airspeed and flap settting and resets the stab appropriately. Either this, or a stab that hasn’t been designed to be uncontrollable manually at high speed.
