I don't think it needs a project of its own. We've been telling people for ages that working "sideways" is usually the fastest way to make connections. And personally, I continue to look for sideways connections, even though my branch is connected to the main tree through at least six different paths now, because often, a new connection brings me even closer to Queen Elizabeth, Kevin Bacon, and A.J. Jacobs, who I still think of as the core connection profiles, no matter how much they change up the actual people listed at the bottom of profiles.
