Thank you. The title should be changed, really. Following an ancient HN custom I've chosen to get annoyed before reading the article, and the title simply isn't true. In fact, it's exactly what GP suggested, which is a perfectly nice way to implement that. (Unless, of course, one day they get rid of that option as well...)
The title was changed, but it's worth pointing out that they updated the article AFTER criticisms in this thread were already made (the original policy did not say you could opt-out):
