I use Pfsense which communicates DHCPv6 leases to Dnsmasq/Unbound fairly easily.

Probably not but for internal resolution a .local or similar TLD is sufficient.

Yes. The thing is, this would be super easy for the ISPs as they already have to maintain reverse DNS for dynamic IPv4 most of the time, so modifying it to also allow delegating to an authenticated DNS secret should be trivial. Eslecially now that ISPs are so fond of giving you big routers.
