Oh, to me, ^ meant “upgrade”, like ‘guix package -u’ but only taking
into account the version number (‘guix package -u’ upgrades if the store
file name differs, even if the version number is the same.)

I think we need a different solution for packages that have several
series.  For instance, we could have:

  (define gnupg-2.0
    (package …
      (properties `((series . "2.0")))))

and that would lead the various UIs to upgrade only to a package whose
version prefix is “2.0”.

WDYT?
