Still, what Gregory is proposing is exactly how it used to be, isn't it. Of course, that was when Keep Rules Simple was a Rule.
How long ago was that? I don't remember ever seeing or even hearing out policy pages with lists of people that endorse them...
If you endorse a policy page, you do so by keeping quiet. If you don't endorse it, you either edit the bit you don't like, or you mention it on the talk page. You can tell if a policy has the support of the community by looking at the talk page and history. That's the difference between consensus decision making and democracy.
