More cave Biomes

There Should be More cave Biomes than just Lush caves, Dripstone Caves, and Deep dark caves. You guys could do Desert Caves where where Every Block is Sandstone instead of Stone and its Variants, and Husks spawn here instead of Zombies. Most ores could have sandstone variants. Or you could do Slime caves with Naturally occurring slime blocks as well as new slime water that gives poison 2 to Players and mobs, but does not affect Slimes. Slimes can spawn in these Slime caves.
