The cases you describe do not require really hard xml parsing. It's trivial. Composing and sending an xmpp stanza is extremely easy. Parsing is easy too. Why you might want it? Well, maybe for the same reason any home router has a built in web interface (despite all the overheads of having a kinda webserver on such device) - for user's convenience and interoperability. And yes, stating that JSON is somehow better than XML for such cases is just... wrong.
