Actually they are not that great. Look at the DDoS mess that UPnP has created and problems for IoT (I call it Internet of trash, as most devices are poorly implemented without safety in mind) folks on all sides.
Are you saying, without NAT or something like that to restrict reachable ports, the Internet, regardless of whether it is with IPv4 or IPv6, is not very secure?
With end to end NAT, you can still configure your UPnP capable NAT boxes to restrict port forwarding.
The fact that I go to a hotel and that AT&T mobility have limited internet reach is a technology problem that we all must work to fix.
Want to run a server at the hotel?
IP mobility helps you, if you have a home agent at your home and you can use IP over UDP/TCP over IP as mobility tunnel.

And, to applications running over TCP/UDP, UPnP capable legacy NATs are transparent, if host TCP/UDP are modified to perform reverse NAT, information to do so is provided by UPnP.
