This one will pitch up more than most; again a consequence of the design. If the crew are made aware of this, is it really beyond the power of the human mind to be ready and correct the pitch? In other words, no need for this system at all.
Actually, with the thrust line higher than previous versions, and the jet outlet further forward, the pitch-up on thrust increase will be less.

But, the MCAS is not there for the pitch-up. It is there to improve the handling qualities at high angles of attack. What Boeing were after was a steadily increasing nose-down stick force as the alpha increased.

Can someone explain to a non-pilot: In what common circumstances would an aircraft actually need to pitch up close to the stall angle, while flying with flaps up? High altitude turbulence avoidance or maneuvering? Tight turns at high bank angle?
There is no circumstance where the aircraft would need to pitch up when close to the stall angle. Such behaviour is considered undesirable. The MAX has a tendency for this, hence the MCAS system to "tame" it.
