As a computer programmer and former engineer, the time-delay between the AOA input, and the 10-15 second activation of MCAS, could lead to oscillatory behaviour. Pilot input may still be needed, along with some training.
Edit: I meant it is not an 'elegant' solution, more a band-aid. And the nose-down trim still needs to be explained to pilots.
Edit #2. Forgot to add that when MCAS 'unwinds' the trim that it previously applied, this is another time delayed effect.
