Could you add options to make backpacks not craftable?
I mean for every single one.
Cause i think it would be cool to let player craft normal leather backpack, and the rest he could obtain by doing quests on RPG servers like.
I have spongeForge server, and i dont have really much option to block crafting 👎

Also on 1.12.2 i can't put in on. Both keys in controls says "DISABLED"

Use CraftTweaker.
