Yeah, that's why I question whether there is something actionable and 
whether this is so much wishful thinking. Somebody did say that they 
took action on it (gmail?), but i'm not sure whether that is a good 
thing or a bad thing. For mailing lists, that would seemingly be a bad 
thing, but if you're of the mind that mailing lists are a security bug 
and not a feature that might be contradictory.
