	I think the anti-587 logic here seems to be that we (we being 
	the Internet community at large) shouldn't encourage anyone to 
	ever act more responsibly than the worst operator because that
	worst operator will continue to be irresponsible.

	(I am only translating, not agreeing.)

	In any case, nobody has expressed any new ideas around this
	topic for about a week, so I'd suggest we let it drop before 
	somebody mis-represents Godwin's Law.
