Support but also why even have flatlands in the first place? Support for the cage or just removing them.
I'm sure it's because it's impossible to MCEdit the entire Flatlands out. But yeah, removing build perms for an area can be done (red on windmill, skyline restaurant mid, etc.) So why not do it for the flatlands, or just make a 256block high cage of white stained glass (not ugly, but unbreakable and can't be gotten around unless the flatlands are really close to it and the player has epearl).
Why are they flat lands even a thing xD And maybe I'll start a post to fix red or something on windmill
