Depends on the aircraft - on ours try and go-round (after touch down) with the prop set coarse
I expect that would be similar to nearly all VP prop aircraft, which is why (I hope) that the flight manual states that the prop is to be set to fine pitch for takeoff, and presumably approach.
I think that flaps, and their possible misuse, are about equal in the possibility of creating an unsafe flight condition at certain times, but flap equipped aircraft don't require differences training? Pilots read the flight manual, and fly the way it says.
There are many ways to create damaging or unsafe conditions by disregarding the flight manual for an aircraft.
