Er; that'd be (for minor modes)

(defun gnus-pick-start-reading (&optional catch-up)
[...]
  (declare (completion (lambda (s b)
                         (completion-minor-mode-active-p s b 'gnus-pick-mode))))

which is a mouthful...

On the other hand, this could go into the `command' spec, if only we had
a way to distinguish minor modes from major modes, which...  we don't
seem to have?  But we could have: `define-minor-mode' could `put' some
property on the mode symbol to say that, indeed, it's a minor mode.

Which could also conceivably be useful in other situations.
