Like you write, this commit is the “wrong end”: it’s about selecting the
package you’re willing to update.

Most entry points in (guix import …) already take a #:version parameter,
which allows you to ask for a specific version when running ‘guix
import’, as in:

  guix import pypi itsdangerous@1.1.0

The goal here is to expose that in the <upstream-updater> API and to use
it in ‘guix refresh’.
