Heavy Core cannot be oriented despite its blockstates suggesting otherwise

It actually can be rotated in the NESW directions but all of the sides are the same. It cannot be orientated Up and Down

The blockstate JSON states otherwise - it only has a default model, with no state-based rotations.

 
{
"variants": {
"": {
"model": "minecraft:block/heavy_core"
}
}
}

Yeah I noticed this too, and the way it's coded made me think that it was an intended feature maybe to add something in the future because it has a bunch of different orientations that I don't think exist in other blocks.

It has all the same rotations as a crafter, yet displays identical for all twelve orientations.
