There have been added [[Special:Wantedfiles]] and [[Special:Wantedtemplates]] recently. However like all other Special:Wanted* pages they are pretty useless, because *links tables have lots of crap rows (some pages and categories are listed, but nothing links to them). Dead links (those from deleted/nonexistend pages) should be removed from database.
What is more [[Special:Wantedfiles]] lists files placed in shared repository... Refreshing such pages is a waste of resources.
