    Sure, but there isn't a big company with clout saying "Hey, you should deviate from RFC791". I agree that standards can and should be replaced/amended to over time, but I kinda see what GP's point is getting at.

      Dropping Via from a response is roughly in the same category as ignoring the TCP Urgent flag. Most widely used standards have vestigial bits.

        A lot of hardware silently edits TOS flags, causing trouble with ECN and diff-serv... Ignoring is usually fine. Dropping is not.
