Apart from the discussion if a ND trim automatism on a detected impeding stall (false or not) is a good choice, I think that any autonomous, severe intervention into the flight controls should always be clearly announced to the pilots. The stick shaker cannot replace that as it is only reporting on a condition of the AC, not on actions taken by it's (autonomous) systems.
Just my 2 cents as a systems engineer in other fields than aviation.
