Cave Carver Generation in 1.17

The cave carvers (being the caves that generated before 1.17) that generate in the new snapshot (and now below y=0) don't seem to live up to the old cave carvers that used to generate. The new cave carvers all seem to be generating disjointed and small and not connected to anything. They seem super rare now, and it is very hard to get down to the lower y-values by just going through caves, as they either lead to nowhere or don't go down far enough. I feel as if bringing back the old cave carver generation and improving the generation from there would be a lot better of an option, as it is nearly impossible to go around caving with these new ones.
