OK, I will do it.
However I think it is kind to ask will you install bin when someone install like gtk+ or glibc with guix package -i <some library package>.

Thank you for your explanation in detail.
I appriciate when I use guix package -i epiphany, guix would recommend additional packages hicolor-icon-theme and adwaita-icon-theme not installed.

And when install fonts, fc-cache is needed.

There will be a lot of files in /gnu/store that are not linked to any
profile.  That’s on purpose.

If you want to install gtk-update-icon-cache you need to install the
“gtk+:bin” package to a profile, e.g. by doing

    guix package -i gtk+:bin

This is also by design.  ~/.guix-profile is read-only because it lives
in /gnu/store (via a series of symlinks).  Nothing in /gnu/store can be
changed; you can only add to it by using the “guix” commands.

The is usually no need to run gtk-update-icon-cache manually as it is
run in a profile hook when building a new generation of a profile.
