Powdered Snow Biome

Powdered Snow should be given its own biome. Like how Gravelly Mountains (on Bedrock, once) were. A unique variant of snow biomes that would actually make Powdered Snow sought out and more of a danger. The Biome should have a top layer of Powdered Snow and can have Powdered Snow Pockets (2 - 5 Blocks deep) scattered around it. This would also make more sense for Powdered Snow [as a biome or top layer] rather than being odd and underwhelming pockets.
