controversial articles and neutrality problems

In a way, all we have to do is propose the recognition of such editors (which makes sense for many reasons not just this one item). The rest can almost be left to individual communities to consider. We don't need to force this area of usage.

In other words, if the recognition of such users is there, and the global WikiProject structure and referee panels exist, and a major dispute is ongoing, the community will have these extra tools to use and at some point will probably decide to do so. Mention it as an ancillary idea or "possible extra use" for those communities wishing to try it. Then leave it to them, once they have the tools needed.
