Smooth cave transitions

The caves and cliffs in snapshot 21w37a do not have a lot of cave in the terrain. I am not saying that there is too little caves, but the caves have practically no smooth entrances to them. Besides the cracks in the terrain most "entrances" to caves are just a one way dead end that go down 10 blocks. Some caves are even just cut up in generation, having one block walls between segments. In versions before (1.16 and below) those entrances to caves where completely find and did not need to be completely removed. There should at least have some entrances that lead you to caves that are more horizontal and not y-level 150 to y-level -24 pits of death. While that is fine to have, I would not prefer to have that be the only way. A good consistent balance of the two could make it way easier to jump into caves and not just strip mining into one or falling down a pit on top of a mountain.
