Caves and Cliffs Switch

So as much as I like the caves and cliffs, it can also be really annoying just because of how deep the caves are. I go to enter one and I almost always die to fall damage. So within the next few updates it would be cool if under the game options when creating the world, if there was a switch for caves and cliffs. Separate so you can have caves or cliffs or both if wanted. This should go in with the section “TNT Explodes” and “Fire Spreads”. This way I can still get my achievements on console. With this players can then have worlds with caves and cliffs and worlds without. I just think this should be something that comes in a future update because I do like the old Minecraft without and I like it with the caves and cliffs so if I could have worlds with neither caves or cliffs. Or even an option with the old Minecraft and the new as a mix would be cool as well.
