The true test is to install and run the extension, which involves installing MediaWiki, if you don't have your own installation already :)

AFAIK, it wasn't deployed on any live site yet, but it may be soon. You can try playing with it on http://test2.wikipedia.org or to try to set up a test environment on https://labsconsole.wikimedia.org/.
