Biome changes

Some biomes, like the Savannah and badlands, just aren't interesting, and I don't think they should be appealing to live in, like the plains or forest. Maybe having some biomes be unique would be pretty cool, like maybe in the badlands their could be a bunch of pillagers wandering around, making it a "harder" biome. Mojang could even change mechanics on some biomes depending on the difficulty, like on easy, the cherry blossom biome doesn't spawn hostile mobs. This isn't really a concrete suggestion, just some food for thought.
