Thanks :)

Well, in my case I am interested only in `load*' and `make-user-module'.  So
maybe I could move them into (guix utils).  (guix ui) could just #:re-export
them in order to limit the size of the diff, but in (guix channels) I could just
import (guix utils) and use the `load*' from there.

Fundamentally I guess the same could be done with `load-manifest' procedure you
mentioned.

Thoughts?

No worries and thank you for merging at least parts,
