Maybe I misread, but it is not possible to refresh packages with
’git-fetch’ as source because of:

--8<---------------cut here---------------start------------->8---
(define %method-updates
  ;; Mapping of origin methods to source update procedures.
  `((,url-fetch . ,package-update/url-fetch)))
--8<---------------cut here---------------end--------------->8---

and

--8<---------------cut here---------------start------------->8---
       (match (assq method %method-updates)
         (#f
          (raise (make-compound-condition
                  (formatted-message (G_ "cannot download for \
this method: ~s")
                                     method)
--8<---------------cut here---------------end--------------->8---

in ’package-update’ from (guix upstream).


Well, it should be possible and as you said: «looks like something is
missing.»  :-)

Hope that helps,
