When you put your app in user/* then it means that you want people to be able to install it. If you then also put it in Extras, then it makes sense to have it in Downloads too. If there are packages in user/* categories in Extras which should not be in Downloads, then something doesn't add up Either they shouldn't be in Extras or they shouldn't be in user/* category. With the whole QA queue, you'd have plenty of time to stop promotion anyway.
