I like Zero's proposal about having twin versions: official and draft. I've thinking about this for several weeks, ever since the nice folks at [[talk:Silesia]] asked me to help mediate.
Perhaps we could protect the official version, and trust admins to move consensus text into it. An alternate or working version could be at, e.g., [[Silesia (draft)]] and purposely left unprotected.
Needless to say -- which is why I'm saying it! -- is that any admin who is a party to an edit war or otherwise is distrusted by those working on the draft, should not be the one to move "agreed-upon" text to the official article.
