Aside from the git note, public-inbox-learn already does that:

   public-inbox-learn spam </path/to/message

   (scans everything in ~/.public-inbox/config since spam is
   frequently cross-posted)

I've been using it since the earliest days of the project and
frequently need it for the git@vger mirror.

It's also wired into -watch via watchspam (but the sa-learn step
to train spamassassin is broken atm).

It appends to git history, v2 changes the 'm' file to a 'd'
file with the corresponding blob; v1 removes the file from the
tree.  It doesn't add blobs to git history, but there'll be
new tree and commit objects.  There's no rebasing at all.

public-inbox-index has always handled unindexing it in mirrors,
too.
