Backpacks

What do you think about adding backpacks to the game?

And yes, I know, Shulker Box...

But hear me out...

What if the backpacks won't be craftables much like the saddle and could be only found in temples, ruins, sinked ships and such.

The backpack would be worn on the chest tab (where you wear your body armor or Elytra) and will add an extra nine-tab row to your inventory.
