FIXME

1) Function check_readiness or event "changed_status" is causing for
   triple status messages and also false ones that indicate of lack
   of feeds.

TODO

1) Use loop (with gather) instead of TaskGroup.

2) Assure message delivery before calling a new task.
    See https://slixmpp.readthedocs.io/en/latest/event_index.html#term-marker_acknowledged

3) XHTTML-IM
    case _ if message_lowercase.startswith("html"):
        message['html']="
Parse me!

            mfrom=self.boundjid.bare,
            mhtml=message
            )

NOTE

1) Self presence
    Apparently, it is possible to view self presence.
    This means that there is no need to store presences in order to switch or restore presence.
    check_readiness
    📂 Send a URL from a blog or a news website.
    JID: self.boundjid.bare
    MUC: self.alias

2) Extracting attribute using xmltodict.
    import xmltodict
    message = xmltodict.parse(str(message))
    jid = message["message"]["x"]["@jid"]
