Note again that the MCAS is there to correct for the light control forces at high angles of attack, not to directly prevent a stall. Even with MCAS version one a deliberate stall entry could (briefly) be possible. As I understand it, MCAS was developed to counter a forward shift in the net centre of pressure, which is kinda like a load shift aft in terms of affecting pitch control forces.
