All the 5 are 'url-fetch' so we can expect that sources.json will be up
before the shutdown on December. :-)

Then, all the 14 packages we have from gforge.inria.fr will be
git-fetch, right?  So should we contact upstream to inform us when they
switch?  Then we can adapt the origin.

It does not work properly if I do not replace by

               ((guix swh) #:hide (origin?))

Well, I have no investigate further.

I am a bit lost about the other discussion on falling back for tarball.
But that's another story. :-)
