They might be overkill for most people, but why make them illegal? I don't buy the argument that more people won't know how to control disc brakes. The people are can't control the extra power of disc brakes are the same people who don't have good braking technique now. The disc brakes won't make them any more dangerous.

If you're afraid of endos, shift your weight back when braking hard, and you will not endo.
