Some of the customization groups in org-mode lack defgroup declaration.
Specifically, they are:
(org-gnus org-startup org-export-pdf org-bbdb org-babel-tangle
org-bibtex org-plot)
In the *Customize* interface, these subgroups are not accessible from
the main Org customization page and vice versa. To reproduce, type
"M-x customize-group org" and witness that, for example, Org Startup
subgroup is not listed. Then type "M-x customize-group org-startup" and
see that the group definition and the link to the parent group are
missing.
Confirmed.
Would you be interested to create a patch? It is mostly a question of
adding a bunch of `defgroup' statements.
