More Cave Biomes

The Caves & Cliffs update was GREAT, don't get me wrong, but I feel like it could be added to. Currently we only have 4 biomes: Amethyst Geode, Dripstone Caves, Lush Caves, and The Deep Dark. This could be vastly added to, by just adding biomes for said biome above the cave, if you're in a Desert, sandstone and mud caves per say, or if you are in say an Ice Spikes Biome, you get ice, snow, and stone in your caves. Take inspiration from Terraria, great game. Their caves have many different biomes, and it helps vastly to add a spark to mining, like fighting Man Eaters, or Cave Bats, or even an Antlion. They are all different mobs, mob variants such as Jungle Bats rather than Ice Bats, and just add something to keep cave exploration from being dry. Adding things as little as a block change for biomes, and maybe some mobs like a Husk to spawn in Desert Biomes. Just imagine exploring in a cave and you stumble across a cave full of Glowing Mushrooms, Vines, Sparkling Water, and beautiful Fireflies. That's the real exploration caves need.
