Wooden Crates, The storage method for aspiring Engineers

I know, I know, we have shulker boxes. "We don't need crates". My goal here is to change that mindset.
CRATES:

Crates would be a storage/decor block similar to a shulker box, aside from a few key things.

• Crates cannot be picked up without spilling all their items.

• Crates can, however, be moved by pistons. If pushed on ice by a regular piston, a crate will slide 10 blocks, or until it is either stopped, or stops touching the ice.

• Crates will fall unless supported. Crates will not fall when in contact with sticky pistons, slime blocks, and honey blocks.

• If a crate lands on an open minecart, it will make a Crate Minecart. The crate can be removed by a sticky block. Crate Minecarts are crafted in the way you might expect.

Crate Crafting Recipe

Crates can be made of any type of wood.

Crates would be useful in many ways, to many types of players. The builder, for decorating docks and warehouses. The redstone engineer, for an interesting way to transport items. The miner, for those long expeditions in mineshafts.
