[MC-307636] In a local area network environment, you can seamlessly switch between different game modes without any cheating or restrictions

It is possible to launch a LAN world by modifying the code or adding a custom multiplayer mod, allowing the host to switch between any game modes freely (including Hardcore mode, Survival mode, etc.) without enabling cheats. Additionally, once switched out of Hardcore mode, it cannot be restored to the original mode. After the host enables cheats, all players (including the host) can switch game modes freely.

Environment

Microsoft Windows11,Any starter and any version
