Cave update 2.0

The cave update could use some work with the addition of biome specific caves. For example the desert caves only go so far they barely scratch the surface which is sad. I believe every biome should have there own type of cave since it could make every world more unique and expands the amount of structures that could go underground. Although, while caves should be updated again I believe they should only reach deepslate caves, with deepskate caves being unchanged to let the player know exactly how far they've gone. The new cave should have different ores spawn more abundantly like in minecraft legends although every ore should be able to spawn. While most cave will be changed, the plains biome should stay the same and the jungle biome should only have additional vines. Next, this second cave update needs more dungeons with unique shapes and sizes. They would also be biome specific with the designs of the dungeons changing depending on the cave. To conclude this update will make minecraft or more specifically the overwold more unique and expansive. Please, someone review this and send feedback and criticism, hopefully someone from Mojang.
