Does it?

Are we talking about the note at the end of 13.13? To me that note is
there to explain why history list SHOULD NOT be the same as cache...

I think only no-store is relevant there.. Expiration and revalidation is
as specified not relevant to history lists.

no-store should be quite sufficient imho.

respecting max-age=0 in history lists would be very annoying, and
inconsistent if handled very much different from max-age=1.

but on the other hand most browsers do not implement history lists
exactly as specified, but instead do load much content from cache when
navigating the history and often even respect expiration.
