true, therefore implying restrictions such as up to III or II could be a solution.

most enchantments don't realy work, it's just cool to have some sort of skin with enchanted matching item, such as, priest skin with a stick with Smite, works well against zombies.

Personaly I think it could be cool to use it to make glowy diamonds and emeralds as gifts. a glowing dragon egg isn't something possibly that bad, that's why there must be some sort of limits or restrictions.
