True, but the user might suppose that using -Q ensures that no extra libraries are loaded. I would have thought that nndiary constitutes an extra library. If it does not and the library is germane to -Q then why omit any mention of it from gnus-extra-headers? I have quickly looked at NEWS for emacs-25.1 but found nothing relevant.
