When you open Special:RecentChangesLinked on a client page with some Wikidata usage and Wikidata changes enabled, you should also see all Wikidata changes which you can usually see in the watchlist (when you watch the page). Instead, you can only see Wikidata changes for articles that are somehow linked to/from the page (categorized in the category).

This is quite similar to T89582 and could be a workaround for T42358.
