Armor Templates Change

I think that maybe armor templates shouldn't be destroyed when used but instead, be put into a broken state like an elytra. Then you would, of course, be able to repair them with related materials. I think this would be better than the copy system that is in the current snapshot as with it being possible to copy templates I feel that they lose some amount of value. I mean imagine If you could make copies of music discs; imagine how less rare they would feel if you could just have 20 copies of Pigstep all because one of your friends found a single copy and proceeded to give them out; that would just ruin the point of music discs and I think this same logic applies to templates.
