Unfortunately it is lacking some teeth because normally opting out of all cookies should be as easy and straightforward as opting in to all cookies, but I've seen quite a few forms that hide 'reject all' behind a 'more info' button type of thing. Maybe I could file a complaint about that, I should look into it.
