Adding "Monoliths" back into minecraft

Monoliths are large areas of inverted terrain (read more on minecraft wiki) that were really cool in my opinion and should be added back as the rarest structure. They only occurred in Minecraft Infdev as a bug but they looked really cool as gigantic areas of land going to the height limit, and with the new deepslate layer and the increased world height I think it would be extremely intriguing to find one in a random area. Also maybe in the world creation menu you could customize the appearance of these, going from the old look of them (Just stone) or a "newer" look with deepslate halfway up. or maybe options to change the reservoir underneath from just water, to lava and much more. Thanks for considering!
