As I pointed out earlier, some of us are adding the message ID in the
footer alrady, using a Link tag.  This is even documented already in
the Kernel Maintainer's Handbook, so I'm pretty sure it's not just me.  :-)

https://www.kernel.org/doc/html/latest/maintainer/configure-git.html#creating-commit-links-to-lore-kernel-org

This is quite sufficient to extract out the full patch series given a
particular patch.  The b4 python script does this this; given a single
Message-Id, it can find all of the other patches in the series.  I
won't say that it it's "trivial", but the code already exists, and you
can copy and paste it from b4.  Or just have your script shell out to
"b4 am -o /tmp/scratchdir $MSGID"
