I created https://www.mediawiki.org/wiki/Help:ChangeContentModel using VE after it prompted me to set up my single edit tab preferences. But it left https://www.mediawiki.org/wiki/Help:ChangeContentModel?venotify=created in my address bar. If that url parameter is necessary, it should be hidden with history.pushState magic.
