At our airline we have a very unusual way of conducting 'manual flight'.
PF assumes the role of 'autopilot', so even though he is flying the aircraft, PNF decides when flap will be selectecd, puts the gear down when he wants, and so on.
It very much discourages hand flying. That is the effect that it has in real life.
Whether that is the intended effect, I know not.
On the rare ocassion that an FO "hand flies", expect a less than jerk-free ride.
