please add backpacks with the storage compacity of a double chest?

The backpack could hold loads of full shulker boxes and would help with inventory management and can be put into chests but can't be put into a shulker box; crafting recipe would be (string at the top right and left of a crafting table, leather at the middle left and right as well as bottom middle of the crafting table, and a chest at the top middle and middle of the crafting table.).

therefore, making this into Minecraft will fundamentally change inventory management for the better in the Minecraft community.
