Superflat survival buffs

Wondering traders that are superflat specific which offer more trades including , iron bars, potions, obsidian if not the bucket of lava, diamonds, bucket of water, etc Also allow for trees and grass customizations, that don’t disable achievements. And small infrequent water lakes. Allow village spawning in superflats, even if spaced out to make them not too common, and pillager outposts, possibly ruined portals but at a lower spawn rate than the overworld.

basically adding superflat customizations, but editing layers can disable achievements, only allowing dirt,grass,stone, gravel, sand, sandstone, air, deep slate, netherrack, bedrock, water, lava, grass, tree spawning, ect will not affect but other blocks adding in layers will ask you if you want to add to disable achievements if your world is selected on survival. Adding other structures that are not villages, pillager outposts, witches huts, desert wells, desert pyramids could also ask to disable achievements, in structure selection which id take inspiration of the Xbox one editions way of customizing, but bedrockify it.
