Let's say hypothetically someone procrastinated too long on the mailing list switchover and missed some messages on openstack-discuss, but now wants to reply to them. Is there any way to do that without breaking the threading in people's clients? Perhaps some way to request a message from the archive to be sent to me (err, this hypothetical person ;-).
Sure! It's *slightly* hacky but looking at the archive of your message, for example:
http://lists.openstack.org/pipermail/openstack-discuss/2018-November/000234....
You'll see that your obfuscated E-mail address near the top is a hyperlink. The "In-Reply-To" parameter content can be turned into a message header of the same name like:
In-Reply-To: <b63bf848-d58f-f461-c47f-53d21bd21d3a@nemebean.com>
...and added to the other headers in the reply you're composing. This should preserve threading for everyone just fine. If you want to scrape it from the HTML, just note that the "<", ">" and "@" characters are %-encoded as "%3C", "%3E" and "%40" respectively so you'll need to decode them before putting them into the header.
Nice, thanks! Dan Smith sent me the thread so I could reply directly, but I did play around with this a bit and was able to send an email with the header present so it looks like that would have worked.
An alternative solution is to visit the top archive index at http://lists.openstack.org/pipermail/openstack-discuss/ and you'll see that next to each month (in this case we only have November so far) there's a "Downloadable version" linked. Following that link will simply bring up a concatenated plaintext version of the month's archive in mbox format (new messages start with "From " at the beginning of the line) and keyword search for the message you're looking for, then copy the content of its "Message-ID" header into an "In-Reply-To" header for your reply.
