No, but if you're saying the proposal is bad because people suck, then AGF does come into it.
Not people in general, just some people. AGF only applies when there is significant doubt. There is no real doubt that a "nominate this article for deletion" button would be abused. How much it would be abused and how easy that abuse would be to deal with is a little harder to determine, so it might be worth giving it a go to find out (this is a case where experimentation won't do any great harm).
