IBTD.  No documented standard with strange variations in syntax in
practice is worse than a clear standard with MUSTs and MUST NOTs.

Morons intentionally violating MUSTard are no compelling reason to
"undocument" Expires:.  And this header field exists in the Mixer
and Netnews RFCs, an attempt to "undocument" the idea is futile.

I think we are at the point where a fresh draft would be helpful.
