Idea for World Generation on Bedrock

I was thinking about how Java had amplified worlds and single biome worlds. I was thinking bedrock should have this too, along with choosing how many biomes a world could have. (For example if someone wanted Cherry Grove, Taiga and Dappled Forest, the world would only generate those three biomes and possibly choose what structures they want in their worlds). It also doesn’t have to be just the overworld. It could also work with caves and the nether too. It would give players a lot more freedom and options to customise their worlds.
