Lock Creative Mode Toggle After Survival World Creation (No Cheats Enabled)

In Minecraft, when a player creates a new world, they are given the option to choose between Survival and Creative mode. This choice defines the gameplay experience — either a challenge-based survival journey or a free-build creative sandbox. However, after the world is created, the settings still allow switching between Survival and Creative modes. This undermines the original intent of the world. For example, if a player selects Survival mode and plays with effort and strategy, they can later switch to Creative mode and bypass all progress — which breaks the integrity of the game. Suggestion: Once a world is created, the chosen mode (Survival or Creative) should be locked permanently — unless cheats were enabled during creation. If cheats are disabled, the game should prevent any mode switching after world creation. This ensures fair gameplay and protects the value of honest progress. Please consider implementing this logic to preserve the challenge and meaning of Survival worlds.
