This is the option I am for.  Even, the patch is ready and waiting since
«Fri, 10 Sep 2021 18:01:22 +0200». ;-)

The patch reads:

--8<---------------cut here---------------start------------->8---
+  (if (eq? method (@@ (guix packages) computed-origin-method))
+      ;; Packages in gnu/packages/gnuzilla.scm and gnu/packages/linux.scm
+      ;; represent their 'uri' as 'promise'.
+      (match uri
+        ((? promise? promise)

[...]

+           (_ `((type . #nil))))))
+      ;;Regular packages represent 'uri' as string.
+      `((type . ,(cond ((or (eq? url-fetch method)
--8<---------------cut here---------------end--------------->8---

and I find better (guix packages) but I do not have a strong opinion; I
accepted previously in this thread to send a v2 with (gnu packages) or
whatever other location.

I do not mind about option (2) which reads:

--8<---------------cut here---------------start------------->8---
+  (if (or (eq? method (@@ (gnu packages linux) computed-origin-method))
+          (eq? method (@@ (gnu packages gnuzilla) computed-origin-method)))
+      (match uri
+        ((? promise? promise)

[...]

+           (_ `((type . #nil))))))
+      ;;Regular packages represent 'uri' as string.
+      `((type . ,(cond ((or (eq? url-fetch method)
--8<---------------cut here---------------end--------------->8---

Whatever.

However, since it is me who takes care about how this sources.json is
generated, I find easier to have one location and forget about this
case.  The only thing I am asking here with this patch 50620 is to
locate computed-origin-method to one unique place.  If people strongly
disagree, then let do this option (2) and move on.

Last, I am confused why all this is so complicated when it is trivial
and for something outside Guix proper.  I do not understand what we are
discussing when my request is trivial, IMHO.

This discussion has eaten all my energy allowed for Guix.
See you next week.

All the best,
simon
