The UA actually shows a prompt when it encounters a 404 if there is a
version in wayback[1].  It seems that both wayback and the UA are acting
entirely within their appropriate boundaries to me, does it not? Your
deletion is indeed honored, but if someone archived that it is indeed
archived.  If you setup your server not to be, it shouldn't be (though it
really still could be).  If the UA offers help in finding that, that seems
really not a lot different than all sorts of a lot of browser features
(like a search toolbar).  Am I misunderstanding something?
