This is completely wrong. Boeing did make the changes to include input from two AoA sensors, they did change the system to prevent recurrent horizontal stabilizer movements, they did include a manual shut-off.
What you are talking about has very little to do with MCAS. Congress required any new aircraft type certified after 2022 to include an Engine-Indicating and Crew Alerting System.
It was never even intended to apply to the 737-10, but because the certification took longer than expected, it became likely the -10 would fall under the regulation, which would cause pilots to have to be re-trained for the -10.

All of this is only peripherally related to MCAS.
