Yeah, but people change. What once could have been a trustworthy chat moderator can start misbehaving in chat anytime. Their account could also get compromised. Administrators that don't know about !kick or !ban wouldn't know what to do in such situations, except block/demote them and wait for the chat moderator's chat socket to die.
