For students I agree. For people who are teaching, I would expect them to take an interest in why they are using the methods they are. It also allows for more specific targeting of training goals. For example, it's one thing to say "unscripted resistance is better than partnered kata", which is fine enough for a student to say, but I would expect an instructor to at least pondered the reason why that is, and the physiological systems involved. If that isn't controversial for S&C, why is it for motor skills?
