It’s the old story with Adam and Chava and touching the tree. Halacha is not Chumra is not Minhag.
Telling someone that there is a “din vchesbon” (meaning something hot, even if you don’tsay as such, they know thats what you mean) for anything not done to according to your standards is a quick way to get kids disillusioned; I know from first hand experience. Telling them that it is beneath a ben/bas Torah and they are better then that is much more effective.
