Hm, looking at '(guix) Packages with Multiple Outputs', we already have
an example, which simply append packages and (list package "output")
lists, so perhaps that should be preferred instead.  The
'specification->package+output' procedure mostly appears to be used
internally, in (guix scripts environment) for example.

Note that for user profiles, it seems better to use manifest with the
convenient 'specifications->manifest' procedure that allows directly
providing package name/outputs via a "bind:utils" specification, for
example.

Closing!

The bind:utils (dig, host, nslookup) are not copied/included in any bin
path.
