Thread:User talk:CodeCat/zh

isn't used in the main namespace, I've replaced it also in the category, appendix and citations namespaces, so all the rest is really talk pages (and so on) most of which should not be replaced (we generally don't edit other people's comments to remove deleted templates). There might be a few to change, but I think if we delete it now that will at least discourage people from using it more.
