	Mind you, this actually happens. Even at current many NSPs
	free-willingly carry alien-traffic. Yet one does not see
	people run aloof on the streets and scream in panic() with
	all their valuables on fire.

	Sure, clearly not a solution for the QoS-sighted, but still
	indeniably a rather high-ranking option for people interested
	in sheer high volumes of bulk-traffic.

	What are we to pick for people what they want. If neither
	discouraged nor eliminated by protocol-design, the provider
	itself is left with all choices as to what to and what not to
	offer for his/her own clients.
