Indeed, you can really choose what to put in the build environment.
See ‘bison-for-tests’ as another example, in flex.scm.
As an end user, you could choose to have different profiles:
$ guix package -i texinfo -i guile
# installs Texinfo 5.2, Guile 2.0.9
$ guix package -p old-times -i texinfo-4.3 -i guile-1.8.8
# installs those under ‘old-times’
