Curse of binding 2 for armour

There should be another level of curse of binding (curse of binding 2) that makes it so that if you have a piece of armor with it when you die the armor stays on you kinda like in Gamerule keepinventory just only with armor that has this enchantment. Of course it should be a very rare enchantment because it's very strong and maybe it should be incompatible with mending to stop it being everlasting because otherwise it would be OP. Of course there should be some other way to get it off but i didn't think of that yet.
