Caves and cliff update that came around 5 years ago or something idk

I wanna get a new update about the caves and cliff which changed the entire world seed generation this means if you try to get a cool seed like mountains and 15 village it won't work so imagine if there was a switch in the advanced setting we're you can turn off caves and cliff that means if you turn this off that means deepslated don't spawn dripstone also don't spawn even moss cave or sulffer caves don't spawn only for biome
