No strong opinion, but this seems a bit redundant with ‘--search’, for
example:

--8<---------------cut here---------------start------------->8---
$ guix package -s guile | recsel -e 'name = "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-maintained
+ 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 ‘--show’ is restricted to exact package name
matches.

WDYT?

Besides, if ‘--show’ were to be added, it should be implemented in terms
of ‘package->recutils’ like ‘--search’.
