Isn't this more of a calendar function than a cleanup function?
If I miss a meeting notice that has an EXPIRES header, I don't
want it deleted, I might want it highlighted so I can apologize for
missing the meeting. And it would be nice if the MUA would slide
soon-to-expire messages to the top of some priority list.
Maybe it's a personal choice, but I don't want a third party being
able to set a firm date-to-disappear on mail in my inbox.

So, what would you want the recipient MUA to do with these. The
consensus seems to be that they should still receive them - so what
difference does the 'expires' make? Automatically moving them into
another folder when they arrive is nearly the same as automatically
deleting them as far as many users goes! Showing them in grey or
another colour doesn't stop people having to read them to see if
they've missed something important.
often you can tell from the subject line whether a message is something
you actually need to read. if the subject line of an expired message is
shown in grey, that's just another clue to help the recipient decide
whether to read the message or delete it.
"confirm your subscription to list X in the next 3 days" is still
important if you receive it 4 days later. Now you know you need to try
again to get onto the list.
right, some messages become _more_ important after a given date...
it's at least possible that ordinary users might eventually learn how to
use such things as expiry dates. for instance, many of my younger,
non-geek friends now seem to understand the value of Bcc. I don't think
that was true 10 years ago.
"I'm out of the office until ..." may be important, you may have been
bad-mouthing a contact because they hadn't replied to you earlier, and
now you'll know why
a good example of why automatically deleting a message based on expiry
date is a bad idea.
"special offer valid until ..." may still be important from the
sender's point of view as a "buy our wonderful flying car for only
$15,000 before 30th July, look how amazing it is..." is still a good
advertisement if it's received on the 1st August, and the recipient
may still want it even though the special offer has expired.
yes, but most readers would not want it. again, automatic deletion is a
bad idea but when the reader sees the summary line of the advert in grey
he'll likely infer that the offer has since expired.
I could imagine looking at the message summary in my ietf-announce
folder and seeing some LAST CALL announcements in grey and others in
black - and that would be useful in letting me know which messages to
(I could even imagine configuring my MUA to show a message in red if the
expiry date were within say three days...but that probably wouldn't be
the right thing for most messages nearing expiration.)
'expires' only makes sense (IMV) if it would reduce the mail to be
read by the recipient by getting rid of stuff that's absolutely no use
disagree. I think it's useful as a tool to help people decide which
messages to read. but my assumption is that other people do like I do
and look at the subject lines of messages to decide which ones to read.
