Thread:User talk:CodeCat/Clearing out Special:Unused templates/reply

I suppose one easy way to do this would be to add it to, so that if transcluded onto Template:NAME, it shows  and checks whether it exists and equals NAME. I'm not certain if this would work though, considering that to produce a language template would have to transclude itself (indirectly, via, but still), which may trigger an error. On the other hand, they already self-transclude to produce the link to the main language category, so this may work. It would be worth trying.
