I see it differently, if some find the pitch forces of a 172 too heavy, that's an extra reason for power idle practice in it (or physical strength building)!
Pilot DAR, that's too smug. The important teaching aims during the landing,for all ab-initio pilots is to: 1. build confidence 2. teach the landing phase 3. learn the sensory and visual knowledge required and of course, and perhaps the most difficult of all, appropriate decision making. They will not learn these things if they are struggling with the controls. Where an individual requires assistance with power then idle landings can follow as a specific exercise. Idle power will be part of forced landing training obviously.
