Superfalt dimensions

I heard about the new superflat dimensions for the chaos cubed drop and i'm not a big fan of it. i don't want this being like 1.16.1 where you reset the nether dimension. Instead it should be an option to have the dimensions flat like having structures enabled. You could also not update preexisting flat worlds so they stay the same. I know Mogswamp and i would not enjoy having to remake all of our farms. To save us from mining twenty-seven stacks of netherite ingots, think about what i've said.
