Equip/Armor Component

I think a component for allowing non-armor to be equipped in an armor slot would be a welcome addition. There doesn't need to be any fancy options like equip sound or armor texture id, though those would be nice. Basically, no need for /item to put banners, lightning rods, end rods, etc on the player's head, they can choose to equip it as they would armor. Also gives some use to armor-slotted attributes on non-armor.
Additionally, banners, end rods, and similar easter-egg head models should by default be able to be put on your head, just not by shift-clicking or right-clicking, so as not to mess up hotbar-inventory swapping or block placing.
