Add the Blockshape property back to Bedrock scripting

Hi, I had an idea of making an epic mod where tons of new blocks get added to the game, some include mushrooms and more stair and slab variants. Pre-1.15 (or 1.14 for Bedrock), creating blocks that aren’t the standard cube shape was possible, and involved a property in the blocks.json file called “blockshape.” However, now that I’ve returned to modding a few months later, I tried creating a mushroom plant by using “blockshape”: “cross_texture,” but the shape did not render. Instead, it was still the cube shape used for normal blocks. I downloaded another addon I knew that used the blockshape property and sure enough, the blockshapes in that addon were broken, too. This must mean that you guys removed the “blockshape” property, and for what reason, I do not know. But I liked the property and now that it’s gone, my entire mod is not going to work, now. For this suggestion, I simply want the “blockshape” property to be added back. You don’t have to make anything new, just add the old thing back.

    Is there any list or documentation of all "blockshapes" properties in Bedrock Edition? It has so much potential.

    Since 1.21.100, custom block "properties" have been removed/blocked in Bedrock Behavior Packs. This change is breaking advanced block-based systems such as Java-style redstone dust, block rotation variants, and model-swapping without using multiple block IDs or entities. 

    Why "properties" were essential:

    • Allowed one block ID to have multiple states (e.g., "shape": "cross", "line", "dot", "corner", "t")

    • Made it possible to sync logic in BP with visual permutations in RP

    • Reduced block ID spam and resource duplication

    • Enabled complex systems like Java Edition redstone dust, rail states, pipes, etc.

    The problem with its removal:

    • We now have to create separate block IDs for each state, causing bigger packs and worse performance

    • Cannot efficiently make Java-style redstone dust in Bedrock

    • Modders are forced to use entity hacks just to change block visuals

    • Breaks many existing maps and addons relying on "properties"

    What we’re asking for:

    • Please restore "properties" in both Behavior Pack and Resource Pack blocks.json

    • Allow them to be linked with block_state queries in RP permutations

    • Maintain compatibility with existing packs while supporting the new component system

    •  // Behavior Pack
      "properties": {
        "shape": ["cross", "line", "dot"]
      } // Resource Pack
      "permutations": [
        {
          "condition": "q.block_state('shape') == 'cross'",
          "components": { "minecraft:geometry": "geometry.redstone_cross" }
        }
      ]

    And This keeps Bedrock powerful for creators while still supporting the new scripting system.
    Bedrock should not lose functionality Java Edition has had for decades.
