Serious question: What is the use-case for email as a server communication protocol rather than say HTTP/s ?

Is it to bypass firewalls in some way ?

Email allows someone to send me data, as opposed to HTTP/S which targets servers. Adding structured data to emails could allow natural language communication to have a machine readable view of the communication. And there's probably a lot more uses.

You'd still have the option to use WebSockets or Ajax-polling.
