Vagrant proposed [1] to add a flag as --machine-readable, quoting:

        I vaguely recall discussing on irc not long ago the desire for "guix
        refresh --list-dependent --machine-readable" (e.g. drop the "Building
        the following X packages would ensure 10 dependent packages are
        rebuilt:") or something similar. Would save having to pipe to cut, awk,
        sed, perl, etc. ...

Well, there is also the annoyance that hidden packages are shown so it
becomes cumbersome for piping with “guix build” for instance.  Maybe,
this patch could be tweaked to have something like,

    guix refresh --list-build-dependent PACKAGE

returning a list accepted by “guix build”.
