Change tags (aka revision tags) allow users to monitor for specific types of edits at Special:RecentChanges and Special:Watchlist. For example, the #mw-blank tag surfaces edits that blanked a page, which is often a form of vandalism. Similarly, we could introduce a tag for edits that add links to disambiguation pages, which could be of use to patrollers who aim to fix disambiguation links.
- Add the tag disambiguator-link-added (English label, "Disambiguation links") to edits that add links to disambiguation pages.
- For performance reasons, this should probably be done in a deferred update or through the job queue.
