This behaviour doesn't come from XMPP. All the presence subscriptions
need to be used for is to determine whether presence stanzas are
shared. Messages are not affected by this.

As I said, I'm only aware of one implementation that goes further and
also enforces a requirement of presence subscriptions for messages to
be transmitted (Google).
