It is completely different: with "-Q", your .emacs file is not loaded at
all, and with "--no-site-file", only the emacs packages from the guix
profile are not autoloaded.  Isn't that what you wanted?

If you want to autoload emacs packages from a guix environment (or
similarly from any non-standard guix profile), you can do it like this:

(let ((guix-env (getenv "GUIX_ENVIRONMENT")))
  (when (and guix-env
             (require 'guix-emacs nil t))
    (guix-emacs-autoload-packages guix-env)))

Sorry, I don't understand your use case (I think I just didn't read your
message carefully enough), but if you think there is something to be
done, please tell.
