caves in experimental snapshot 2

while playing in both creative and survival on the new experimental snapshot 2 I noticed a major difference between 1.16-17 versions. entrances to non-water caves are extremely rare and hard to find, this in turn can effect game play. when loading into a new world you don't go find a cave and keep going until you go back to the surface, now you must dig down and strip mine which isn't much of a big deal. it just kind of takes away a certain experience and easiness from the game.
