What's the point of servers?

I really dig the aesthetic of the Hario V60 Barista Server, but I don't see any advantage over just setting a v60 right on top of your cup. Seems like extra gear for no gain. If anything it loses heat going from the server to the cup. Am I wrong or missing something here? Is it just for serving more than one cup and I suppose ability to give the brew a lil swirl first?
