Ok.  I do not find it better than (guix packages) where 'origin' is
defined but anyway.
I will send a v2 considering this and the rename you proposed.

This patch is not about discussing if this method should be public or
not.  It is private.  Please discuss that elsewhere.

The reason 'computed-origin-method' is not exported is because it
never went through the review process that such a radical new capability
in Guix should go through before becoming part of it's public API.

and this patch is about improving the situation (by removing the code
duplication).  That's all.  The aim of this improvement is related to
saving these IceCat and Linux Libre packages by Software Heritage [1].

As I said, the point of my patch is not to discuss if this
'compute-origin' should be part or not to the public API.  It is
simply a cleanup to ease the patch#50515 [1].  Therefore, I do not see
what is the point to create its own module.

All the best,
