Use-case:
I'd like to use Special:RecentChangesLinked to filter the recent changes to articles that are associated to a particular WikiProject in Wikipedia. This would allow WikiProject members to more effectively patrol edits to pages related to their subject matter interests/expertise.

Proposal
It's a common practice in Wikipedias to have WikiProjects "claim" articles using links to categories. Special:RecentChangesLinked is capable of using such categories to filter the RecentChanges feed. However, categories are usually added to article's associated talk pages.

While Special:RecentChangesLinked has an option to include edits to the "Associated namespace", selecting this option does not does not result in Article changes being included. See this query as an example of what I thought would work.

I propose that Special:RecentChangesLinked be altered to include edits to content namespaces (even numbers -- e.g. 0) when the talk namespace (odd numbers -- e.g. 1) are linked to the target page (e.g. Category:WikiProject Biology articles) and the "Associated namespace" option is selected.
