Not the only benefit. UP&P lets us port forward, and find our IP. Both
are valuable; the former lets us do invitations, for example, without
having to do darknet ref exchange in both directions. It also lets us do
opennet bootstrapping; any node which is a seednode will have to be port
forwarded. And it lets us do HTTP-based invites, TCP transport, and so on...
