Old world type before caves and cliffs

I know people do not want the old villages back except me, but can we at least bring back the old-world gen?  Like before caves and cliffs? Oh and please make extreme hills spawn constantly again please. I don't mind the new biomes or the deepslate layer, but can we just get the old terrain back? Not the 256x256 one though. By the way I am specifically talking about the terrain from when the textures were still old.
