Indeed, which is why it's typically not done, there are many better XMPP clients with debugging capabilities (including command-line ones) than telnet. Personally I much prefer debugging XMPP to debugging IRC protocol issues since it's always obvious what is going on from what goes over the wire, whereas in IRC you are frequently forced to look up random specs to figure out what some obscure numeric code means to a particular implementation of the protocol.
