For a practical test, search for kbin.social (and then ctrl+f for it also to get the direct results). Or, just look at a community: !kbinMeta@kbin.social

The only thing that appears missing is the avatars. Though I assume this content is doomed in the long-run when it comes to new instances, as I doubt re-federation (3rd-party federation) is a thing. Unless of course, someone manually crossposts said content.
