Armor Variant That Cannot Be Picked Up By Mobs

This is a variant of armor/weapons/tools that is created by upgrading diamond gear at a smithing table, like netherite but as an alternative to netherite. Instead of immunity to burning up, this variant would be unable to be picked up by mobs. This would be a benefit that, like netherite, would help prevent gear from being lost when the player dies, but it would be helpful in places where fire or lava is not nearby. I know picking up gear makes mobs persistent, but a mob that picks up your enchanted sword becomes much more dangerous to fight or might wander away, so gear can still be effectively lost if it's picked up by a mob.
