Option to permanently lock Operator and Creative mode in a Survival world

Title
Option to permanently lock Operator and Creative mode in Survival worlds (with retroactive support for existing worlds)

Description
Currently, when you create a new Minecraft world, you are automatically set as an Operator. This means you can accidentally enable Creative mode or use commands, which immediately disables achievements. Even a single mistake can ruin a long-term Survival experience.

Proposed Feature
Introduce an option called “Lock Operator and Creative Mode”.

When enabled:

• No player can become Operator

• Commands cannot be used

• Game mode cannot be changed

• Even the world creator cannot disable this lock

Important Details

• The option should be available when creating a new world

• It should also be possible to apply it to existing worlds, so players can protect worlds created before this feature was added

Once activated, the lock is permanent, ensuring a true Survival experience without accidental cheats or disabled achievements.

Benefits

• Prevents accidental mistakes in the menu

• Eliminates the temptation to cheat

• Keeps achievements intact

• Perfect for solo Survival and private multiplayer worlds

This simple feature helps keep Survival mode authentic, secure, and enjoyable for everyone.
