[02:01:00] for the record, DT is already enabled on that page. This happens automatically if DT detects there are discussions on a page. One of those signs it uses is talk namespace. Another sign it uses is the "Add topic" button (__NEWSECTIONLINK__). Adding that, as this page already does, makes MW core understand it as a talk page and add "Add topic / New section". And DT listens for the same signal.
