customization of old console versions in bedrock edition

An example of this would be the old versions of Minecraft on consoles (Minecraft: PS3 Edition, Xbox and more) and you could make a customization of the world, how many blocks could there be below and that there would be a limit of 2000 blocks so that it is not only 3 blocks and get to the bedrock fast, this could be a good thing for builders and for those who do not know how to use commands to make thousands of blocks of dirt
