tl;dr: You are *very* likely not affected. We are planning two changes in the REST API: 1) Remove the experimental /page/html/ and /page/data-parsoid/ listings [1][2]. Our metrics show that these are essentially unused. The same title listing remains available at /page/title/ [3]. 2) Make the `tid` path parameter in the unstable /page/data-parsoid/{title}/{revision}/{tid} [4] end point mandatory. Data-parsoid is tied to a specific HTML render, and only requests with an explicit timeuuid from the corresponding HTML response are guaranteed to get the correct data-parsoid version. If things go to plan, we will deploy these changes sometime next week.
