I know it was already mentioned, but some features were recently added
to piem (patch waiting over at https://issues.guix.gnu.org/64155) to
integrate it with debbugs.el, the Emacs debbugs interface. This makes it
(IMHO) a fairly easy to apply some patches locally.

I have this set up with (something similar to) the following:
--8<---------------cut here---------------start------------->8---
(setq piem-inboxes
      (("guix-patches"
        :coderepo ("/home/jlicht/Documents/guix")
        :url "https://yhetil.org/guix-patches";
        :listid "guix-patches.gnu.org"
        :address "guix-patches@gnu.org"
        :gnu-package "guix-patches")))

(require 'piem)
(piem-gnus-mode 1)
(piem-debbugs-mode 1)

(require 'debbugs)
(defun debbugs-gnu-guix ()
  "List Guix issues."
  (interactive)
  (debbugs-gnu '("serious" "important" "normal") '("guix-patches") nil t))
--8<---------------cut here---------------end--------------->8---

With the configuration taken care of, just `M-x debbugs-gnu-guix',
navigate to any issue (just put point on an issue you are interested in)
and run `M-x piem-b4-am'. It should pull down all needed messages (from
yhetil's public inbox mirror), and use some heuristics to apply the most
recent patch revision, taking into account either 'git send-email' or
attachment-based patch series.

Hope this additional data point is useful.
