I believe the key package that the first emacs-commander (the one before
--ad-hoc) brings in is emacs along with its corresponding EMACSLOADPATH.
Notice that
$ guix environment --pure --ad-hoc bash emacs-commander -- sh -c 'echo
$EMACSLOADPATH'
outputs nothing. Now if emacs is added as an ad-hoc package:
$ guix environment --pure --ad-hoc bash emacs-commander emacs -- sh -c 'echo
$EMACSLOADPATH'
/gnu/store/qg6rsw6w587aykln2dzssr43nl6jq1a1-profile/share/emacs/site-lisp
Or another test, dropping --pure to be closer to your initial snippet:
$ guix environment --ad-hoc emacs-commander -- \
emacs -Q --batch --eval '(print (locate-library "commander"))'
nil
# add emacs as ad-hoc package
$ guix environment --ad-hoc emacs-commander emacs -- \
emacs -Q --batch --eval '(print (locate-library "commander"))'
