I initially didn't send it to git@vger, only to Jonathan. :) I don't mind, though -- I just wasn't sure if this was something others on the git list would care about.

No, this is specifically for GGG mail, as it's a very specific well-understood case. The solution I have in place is to just pay attention to the in-body Form, but once we upgrade to patchwork 2.2.2 tomorrow, we will also start paying attention to the X-Original-From header.
I'm not 100% sure if it's always correct to pay attention to the in-body From -- at least for the purposes of patchwork. Patchwork pays attention to "who submitted the series," not "who authored the commit," so making in-body From always be the "From" in patchwork would be wrong.
For the cases of GGG, we can ignore this difference, as we definitely don't want to pay attention to "who sent the patch" (it's always gitgitgadget@gmail.com). However, GGG can make the situation more correct if it starts adding an X-Original-From that would be the Github name and email of the person submitting the pull request. E.g.:
From: D. Eveloper via GitGitGadget <ggg@gmail.com> <- DMARC From
X-Original-From: D. Eveloper <github@email.here.com> <- Patchwork From
Subject: [PATCH 1/10] ...
From: A. Nother-Person <foo@example.com> <- Git From

It's a reply to another patch, so patchwork only processes it as a comment. Generally, patchwork doesn't see worrying about this thing as its job -- it just wants to let maintainers track incoming patches and series and download them in a format that is easy to apply using "git am". For that matter, that's how b4 approaches this as well.
