Consider the case of the Expires: header in marketing email,[1] indicating when a message should be hidden by the UA or deleted by the server. You would not want a reply to be hidden based on an old Expires: header. And a more interesting use case (to me)... what happens when a sender's UA specifies one Security: header, and the receiver's server adds a different Security: header? What does the receiver's UA display?
