Hamachi had its place back in mid-00's, but I agree that a need for zeroconf LAN bridging has gone down substantially since then. I do think however that extracting its p2p tunneling bit into a separate service could be a good thing to do even now. Its NAT punching was server-driven, which was (and still is!) a superior way to do it. Better timing, tighter port prediction. Heck, it could even establish _TCP_ tunnels through the simultaneous open trick.
