That is true - but there are instances where you want the style available to a user, but you do not wish them to be able to select it. An example is my mobile detection hack. The style must be user selectable for this to work, but you don;t want PC users to select it. Or if you are developing a style on your site and you want a standard user/guest to be able to use it for testing, but don't want it showing up in the style selector..
