Ok didn't realize it was this new thought it would have been in "Labs". I guess that explains why it has no documentation unlike the other other features. Anyway it seems to make no difference to the infobox's on The Division wiki.
That's indeed using the Portable Infobox syntax, but it's not a really great example of a Portable Infobox. It's calling something older (namely a remix of a Classic Infobox meta-template), rather than making its own results (which is the preferred way of doing things). Either way, it's using Europa.
