Describe the bug

Additional context

It mostly for security reasons as bad actor can create command with duplicated name to avoid detection. It for example can happen in polish gamemode "pystories" where certain commands such a "admins" are excluded from logs. Because often owners of such servers are not aware of danger and they have not trusted resources someone can create mailicious command with the same name to do not raise suspicious.

It is not only good anticheat that provide protection for servers, but also good api that prevent weird behaviours.

I know this is breaking change, but it is very easy to update resources.
