   All these things apply just as well to a :group value you specify

The docstring should at least point out that this group might very
well be bogus.

   I believe that what should be emphatically documented in the
   docstring of define-minor-mode and all other places where
   define-minor-mode is documented is that an explicit :group should
   *always* be given.

On second thought this might not be 100 percent universal.  It is
possible that in some cases the (global) minor mode should not have a
defcustom to begin with, because enabling it permanently makes no
sense.  Maybe the hook variable should nevertheless still have a
defcustom with a real group in this case.  define-minor-mode does not
seem to provide for these possibilities.  I believe that
define-minor-mode and maybe define-generic-mode are trying to automate
things that can not be automated.
