Perhaps, but I see getting an RFC revised or written as a long-term
project.  What are we going to do for MM2.1?  And by thinking it
through and er, creatively interpreting the existing RFCs, I believe
we can establish some useful standard practice, that may eventually
end up in a revised RFC.

So, to summarize, my proposal is:

- List-Id: is included in all messages pertaining to a list, including
  both postings and admin messages.

- List-Help:, List-Subscribe:, List-Unsubscribe:, and List-Post: are
  added only to postings.  (Oh, and optionally List-Archive:).
