Great, thank you.

Ideally we’d have a single ‘guix publish’ implementation, or at least
most of it would be a module shared by both ‘guix publish’ and
‘nar-herder’ because it’s tricky enough that we’d rather not have two of
them.  The (guix narinfo) module you introduced is a step in that
direction and as discussed earlier, we need to go further.
