But, it is a part of the three-year-old culture that could be problematic with federation, and has been a topic of debate because of that. We just always post an actual link to the topic cause that’s more interesting and informative than just seeing a screenshot. (Plus if you don’t you’re a lib.)
/Edit - What’s even funnier in all this is our devs just happened to be working on un-forking our pre-federation codebase to a point where we could federate when the Reddit exodus happened. They even announced it something like a week beforehand, but IIRC the main point was in being able to integrate all the nice upstream improvements.
