Lock Difficutly and Lock Cheats Off

It would be really awesome to have an option (Bedrock) to Lock the Difficulty, like Java and also Lock Cheats Off so they can be never activated in the world, because someone could ruin a survival world easily by turning cheats on when the owner only wants them off and wants achievements (if that makes sense) :)

Turning everyone's permissions to "Member" isn't a perfect solution to this in my opinion.
