Iron golems can't spawn on powder snow

Reading the unobfuscated code of the logic used to decide whether a block is valid to spawn a golem on when villagers panic I noticed the game checks if it is either a solid block or a block of Powder Snow. I tried to make a farm using this mechanic, but all tests in-game failed. After some more digging I realized that while this check passes no problem, other checks further ahead don’t.

I post this bug report since the intent seems quite clear in the code for this to be a feature.

These are the relevant paths in the code:

• The strategy that intents to allow the spawning: net.minecraft.util.SpawnUtil.Strategy.LEGACY_IRON_GOLEM

• The check that fails: net.minecraft.world.level.block.state.BlockBehaviour.BlockStateBase#entityCanStandOn in net.minecraft.world.entity.animal.golem.IronGolem#checkSpawnObstruction
