Is it necessarily true that you have to use the stabilizer for MCAS? Would implementing a stick pusher instead fail to avoid some stalls?

It's true in the case of the 737 MAX where the pitch-up moment caused by the engines exceeds the elevator authority in a low-speed, high-thrust situation if the pitch trim is also set too high.
MCAS will evidently work with less maximum nose-down trim than the current version has, as the proposed update places a limit on it.
