I understand the 737 (at least since the CFM56 variants) has been somewhat pitch sensitive to power changes, but I'm curious about the underlying need for MCAS, as per this article:

At high angles of attack the CFM Leap-1B’s engine nacelle generates its own lift.
(source: https://theaircurrent.com/aviation-safety/what-is-the-boeing-737-max-maneuvering-characteristics-augmentation-system-mcas-jt610/)

It must be quite an increase in moment to justify a protection system.

Only a singular AOA input. and a failure mode that might be riskier than the problem it is trying to solve? Hmm...
