No strong opinion, but this seems a bit redundant with =E2=80=98--search=E2=
=80=99, for
example:

--8<---------------cut here---------------start------------->8---
$ guix package -s guile | recsel -e 'name =3D "guile-cairo"'
name: guile-cairo
version: 1.4.1
location: gnu/packages/gtk.scm:424:2
homepage: http://www.nongnu.org/guile-cairo/
license: LGPL 3+
synopsis: Cairo bindings for GNU Guile
description: Guile-Cairo wraps the Cairo graphics library for Guile Scheme.
+ Guile-Cairo is complete, wrapping almost all of the Cairo API.  It is API
+ stable, providing a firm base on which to do graphics work.  Finally, and
+ importantly, it is pleasant to use.  You get a powerful and well-maintain=
ed
+ graphics library with all of the benefits of Scheme: memory management,
+ exceptions, macros, and a dynamic programming environment.
--8<---------------cut here---------------end--------------->8---

One advantage is that =E2=80=98--show=E2=80=99 is restricted to exact packa=
ge name
matches.

WDYT?

Besides, if =E2=80=98--show=E2=80=99 were to be added, it should be impleme=
nted in terms
of =E2=80=98package->recutils=E2=80=99 like =E2=80=98--search=E2=80=99.
