737 MCAS was intended to account something that should rarely occur - the pilot flying the aircraft into a near stall condition. So MCAS would rarely come into play - again, a different design requirement.
Not excusing the sloppy engineering that resulted in the original MAX MCAS implementation, but comparing it to the KC-46 MCAS is apples to oranges.
Thank for that reply, TIL. That distinction is pretty big, but I never saw it mentioned in anything I read...
