In any case, I suppose you can make the argument that only a few people are trying to access their home network resources remotely other than via some sort of proxy/rendezvous service. However, I would argue that such services exist solely to provide a workaround for the deficiencies in the network introduced by NAT. Get rid of the stupid NAT and you no longer need such services.

You do not remove the locating service, what you remove is the remote
proxy service.

For example with a webcam on IPv4, you would connect to website to
download the video.  The camera would also connect to the website to
upload the video.

On IPv6 the webcam would connect to the website to say that it is
alive and what its IP is.  You would connect to the website and your
computer would get the IP and directly connect to the webcam.  If
there were multiple people connecting, you may even be able to use
multicast.
