Unable to set void generator for Nether

This Microsoft Learn article indicates that you can set a void generator for the Nether and End using a behavior pack: Data Driven Overworld Height and Void Generation

Summary is you create a behavior pack, and add a json folder under the "dimensions" folder with the following:

{
    "format_version": "1.19.0",
    "minecraft:dimension": {
      "description": {
        "identifier": "minecraft:nether"
      },
      "minecraft:generation": {
        "generator_type": "void"
      }
    }
}

For the Nether though, if I do it like suggested here, it complains "[Blocks][error]-Void | dimension json file is malformed: -> minecraft:dimension -> components: missing required fields: [minecraft:dimension_bounds]". If I go ahead and add the dimension bounds component, it says "[Blocks][error]-Void | currently only "minecraft:overworld" is supported by behavior pack dimension data"

So it seems this currently isn't supported for the Nether or it is broken.
