It's equally reasonable to disobey "no trespassing" signs if you plan
to avoid making a mess. In both cases, however, you're using a
facility that is somebody else's property, and in both cases you may
inadvertantly cause problems for the person who has the right to use it.

That's true. In fact, they're equally property of the author(s) (in
the wording of RFC 822 and reaffirmed by 2822), and I detest mailing
lists that insist on munging the Subject header, too. Even this
one. If an MUA can't do the right thing based on the List-*
headers, I want no part of it, not even to share a mailing list with it.
Of course, unlike "no trespassing", there are no courts to enforce the
RFCs. But don't let that fool you. They are "legislation", the
product of the skull sweat of dozens of "representatives" far more
competent and hardworking than my Congresszombie, tested in practice,
introduced and maintained through the cooperation and hard work of
hundreds or thousands of programmers, distributors, and sys admins.
The social contract says "These headers are for the use of authors",
and you (as a list admin) want to hijack the "Date" header.
You say "well, it would be very convenient if I could use these
facilities for my own purposes". I can't blame you for _wishing_;
still, an honest man would create an appropriate header _for the use
of the mailing list manager_, and then lobby and write the software to
get it accepted and diffused through the community.
Specifically, you could use either an X-List-Sequence-Number header or
an X-List-Receipt-Date header for your purpose. Teach the archivers
about them (and the versions without "X-", since of course you'll
submit an RFC, right?) for the benefit of web readers.
Re your examples:

You don't. You've already proved that. But authors will care, if
they are not responsible for the stuckage, and they look like idiots
because their post was written without the benefit of a week's worth
of further information, but nonetheless appears with a current date.
Steven> As I said, I can guarantee messages from the future are
Steven> wrong. Disagree?
Depends on what you mean by "wrong". Your server may very well change
the interval between, or even the order of, two posts from the same
(ie, consistently translated) future. Whether this information is
interesting or not is another question; you are, however, destroying
it, and there's nothing in the RFCs that permits you to do that.
