Would love to see a full-block energy diode that can be used to transfer power through a wall without creating holes or breaking immersion; I'm aware wires can phase through walls, but I'd rather not do that. It should be considered a solid block that prevents light from passing through it.

I dont get why its such a problem to have the wire pass through walls, just put a connector on either side of a block and connect the wire, you wont even see the wire

Actually there are other use cases. Placing a connector on a Mekanism Universal Cable looks wrong.
