The headers > are irrelevant to mail routing. I never claimed otherwise! Marc was talking about adding a header for a filter to use.

Postfix cannot tell whether it received a message because of earlier expansion of a list or because of a Bcc: recipient. My point was that you would not want to have a header which disclosed all recipients because that would break the Bcc: privacy. I agree that the alternative of producing seperate copies for each individual user does not seem like a desirable solution either.
