[Operators] public XMPP service: [jabber.sk]

If every XMPP server runs its own CA, then how is that different from
every XMPP server offering a self-signed certificate? All of the certs
will be issued by unknown authorities, thus making life difficult for
end users (those scary security warnings!) and reducing the
effectiveness of using common CAs (which can be bundled into operating
systems or cert-stores and therefore re-used by clients and servers).
