It used to be but not anymore.  Now all minor-modes defined with
`define-minor-mode' (which see) are turned on when passed no argument.
Thus

  (add-hook 'some-mode-hook #'some-minor-mode)

will always enable some-minor-mode.

The toggling behavior is only active in interactive calls or from lisp
if you provide 'toggle as argument.
