The MCAS system likely will never be seen operating by a 737 MAX pilot in their entire aviation career so it isn't like it is making the plane fly the same on a daily basis for type rating purposes or something.
As has been discussed to death in the main accident thread, MCAS is there to counteract the decreased aerodynamic pitching moment stability vs. alpha, not the thrust-pitch coupling effect
