If commands prefixed with "!" or some other character can be sent to the server without being displayed in the chat it would likely be possible to create a simple, weak verification system. The player enters "!mysecretid", the server checks against a list of known ids and users, and sends a public message to all users confirming the player's legitimacy.
Problem is the same player sending the command could be running the server. They could edit their list to allow them to credibly impersonate other players by using false ids.
I don't know if we'll ever have an account system. If we do it'll likely have a centralized list of users and would probably have to be closed source(Servers are already closed source aren't they?).
That being said, I think the ability to send simple commands to the server to execute scripts should and will be put in at some point.
