This is at least the fourth list that DoT discovery over DHCP has been discussed (see DoH, DNSOP, and DRIU).

In the previous three times, it was rejected as not a trustworthy source.

Willem and I wrote a draft on DHCP options that was well received by DHCP experts but not well received by DNS folks.

https://tools.ietf.org/html/draft-pusateri-dhc-dns-driu-00 <https://tools.ietf.org/html/draft-pusateri-dhc-dns-driu-00>

We presented it at IETF 102 in Montréal (July 2018). Looking at the DRIU mailing list, both Martin Thomason and Ted Hardie were active and so you may remember it and the poor reception it received. Our slides are here:

https://datatracker.ietf.org/meeting/102/materials/slides-102-driu-dhcpv6-dns-discovery-00

This draft could be easily revived but that doesn’t change the objections we received back then.

I think Ted Lemon led the charge against this. Here are his slides:

https://datatracker.ietf.org/meeting/102/materials/slides-102-driu-when-to-use-dhcp-00 <https://datatracker.ietf.org/meeting/102/materials/slides-102-driu-when-to-use-dhcp-00>

and here is the video presentation. Ted Lemon starts at 33:13
