Air carvers were removed, can we bring them back, or at least replace their function?

In MCreator 2025.1, the "All positions carved by air/liquid carvers" placement for features was removed.

I'm sure there are reasons for this (I'd like to hear them), but this placement allowed you to generate any feature in mass inside a chunk.

I myself have used this to recreate the stone-deepslate separation of the overworld but for custom dimensions.

If we cannot have the air carvers back, can we at least get a layered generation feature placement? As in, "Layer between <height> and <height> of <Block> replacing <BlockList/Tag>", so we can do this the intended way?
