It looks good. Go ahead.
Topic on User talk:Shirayuki
By making this edit, you added the template page Red link to the category Template documentation pages, but you stated it'll be easier to translate the documentation.
@Keyacom: I don't see what the point of this is, given that Special:WantedPages is already not clear due to various artifacts from the translate extension.
@Pppery: I wanted to create a template that, as described above, can remove MediaWiki:xyz from the Special:WantedPages. But for what you described, I redirect you to another topic.
My point is that the existence of {{Red link}} to remove one entry is premature until the broader problem described there, consisting of many more entries, is solved.
