MCAS will never help any pilot in real life. Too slow.
(For those who would like to see instead of visualize what "too slow" means, I posted a link here, guess it will not work, the youtube thing is called "Boeing 737NG horizontal stabilizer jackscrew cycle").
So as far as I'm conerned, they can include as many conditions as they want, the more the better. They could go ahead and disable it after the certification flight completely. It would be best. Any "help" that helps you "intermittently" is not a real help.
