Superflat customization for Bedrock

This isnt much of a new idea as we have experienced customization types of features since the console editions but it would be super awesome to have some love thrown toward this mode in Bedrock. Superflat worlds turn off achievements and would technically count as a cheat mode (same as creative), it would make sense to reintroduce customization features for superflats. Adding structure generation, block layer customization, biome manipulation, and many more. It is understandable that a superflat is seen as the testing grounds for creative brainstorming but it wouldn't be overshadowed as it can still be an option, just with an expansion for those who want to mess around. If not for superflat then please add some world generating features to other aspects of world creation on Bedrock Edition.
