"Code-Based World Transfer System".

Good afternoon! I would like to propose a much simpler system for transferring worlds between different devices without using a Minecraft Realms subscription. It would be great if there was an option in the settings of each world that would generate a unique code. And on another device, in the "Play" menu, you could select the "Take World" option, enter this code, and also switch a special chain that would be responsible for synchronizing progress. If it is turned on, then the world is transferred completely along with achievements, and if it is turned off, just a backup copy is created. This would greatly simplify the life of players.
