Keep Caves and Cliffs an option

I personally don’t care for the new caves that they are adding to the game and I would prefer if they kept the world generation an option, like how it is now. I personally liked how simple it was to go exploring in caves and strip-mine without going into giant caves and having to worry about fall damage. I also think that diamonds are a reward for looking for a long time and not going into a big cave and finding a lot super fast.
