Look up RFC 6106 (published 15 years ago). Router advertisements have carried DNS resolver info for a long time now.

Once again, the old adage “IPv6 haters don’t understand IPv6” applies.

As much as I would like hosts to use the local NTP server, most will ignore the NTP server you specify in DHCP anyway, so it’s kind of a moot point.

Edit: RFC 6016 actually supersedes RFC 5006 from 2007. That’s nearly two full decades we have had DNS info in RAs. That’s the year Itanium2 came out (any greybeards here old enough to remember that one?)
