The trivial update protocol isn't a standard protocol, and doesn't do what we need it to do. In order for services to be discoverable on the homenet, they have to publish their contact info on the homenet. The protocol that everyone uses for this is DNSSD. This is how you find your printer when you want to print to it. Nobody uses the ad-hoc DynDNS protocol for this.
What the DynDNS protocol does is to allow you to track the IP address of your home gateway using a single A record in someone else's zone (e.g., dyndns.org). It doesn't let you populate your own zone, and you can't do service discovery on the resultant DNS entry, because service discovery is a bit more complicated than that. It's certainly true that we could use an HTTPS-based protocol for setting up delegations for the forward mapping zone. This makes a great deal of sense, since the forward mapping zone shouldn't have to be tied to the ISP. The reverse mapping zone has to be delegated by the ISP, so we might as well do it in a prefix delegation transaction. So if you are advocating this second thing, that makes sense, and we should definitely talk about whether it makes sense to do it this way. If you are talking about the first thing, then maintaining a zone in the homenet is definitely a requirement. Also, think of the privacy implications if all of the services on the homenet had to be discovered from a shared zone like dyndns.org.
