One issue is that such an updater will introduce frequent false
positives. It is common for Repology to get the latest release wrong,
because some distribution is doing fancy versioning, or because
different distributions disagree about what is upstream.

I don't think we can rely on Repology's "newest" status. The updater may
need to provide its own version comparison tool, because Repology's tool
and Guix versioning do not play nice, in particular when using
`git-version'.
