I think we're talking past each other. MCAS is stability control which a lot of planes have and is allowable to pass certifications.
However MCAS also makes the MAX behave like the older design which specifically led to the gap in training and controls over the system. If they just had stability control but without the emulation of behavior then there would be new training and certification, which is something they wanted to avoid but would've prevented these accidents.
