>Not a thing in Minecraft, but the mod adds that

Did you read my post? I'm saying that Bedrock has mod support built in with public documentation. There are a bunch of hooks. You can add new blocks. You can make things happen when clicking in them. You can add brand new items.

Yes, it's night and day as I said. Take the most fundamental naming element of Compact Claustrophobia - the Compact Machine. This is a block which has a pocket universe inside, we have to be able to make this, place it down, enter and exit, and have the inside of the block continue running because after all the outside is still here with us, and also the edges of the outside block correspond arbitrarily to portals inside the block for transmission of... oh right yeah, Bedrock doesn't even have a electrical power system...

With the approach they're taking in Bedrock maybe the Compact Machines I was first playing with years ago become possible (if somebody puts in a lot of labour) in ten years, or in twenty - if sanctioned. But they've existed for years in Java, so why bother?
