As a developer, I want to investigate the work required to fulfill the goals of this ticket, so that we can determine the technical prep required for this work.
When a redirect is converted to an article, it gets sent to the new pages feed (//was recently broken and then fixed in T223828//). We would like to expand on this logic:
* If an article-from-redirect is reverted back to a redirect, it currently needs to be re-reviewed. It should automatically be marked as reviewed, since that version was already patrolled.
* The opposite, where an article is converted to a redirect and back. Again it should be automatically marked as reviewed.
* This ticket is dependent on T157048 first being completed.
Essentially, the system should automatically detect that the page was reverted to a previously patrolled state. This is only applicable when a redirect becomes an article and vice versa.
