In a consensus process, it is not unusual or uncommon for the group to expect a justification for a topic seeking consensus.

To the best of my knowledge, those same questions have been asked about all of the IPv4 protocols in the IETF development process, too.
If he wants to just go mod his DHCP daemons, he’s welcome to do that. If he wants IETF consensus around a change to the DHCP protocol, then it’s not at all unreasonable for him to have to justify that position to the IETF.

Sure, but here’s where you break down…
The current situation isn’t attributable to “the current IPv6 crowd” (whoever that is), it’s the current IETF consensus position. Changing that IETF consensus position is a matter of going through the IETF process and getting a new consensus. That requires justifying your position and convincing enough people willing to actively participate in the working group process of that position.
I like to think that I would be part of almost any valid definition of “the current IPv6 crowd”. While I do think that RAs are a better mechanism for most situations, I also support the inclusion of information equivalent to RIOs in DHCP options.

It shouldn’t be one stupid field, even if we do put it in. It should be an additional option for providing zero or more RIOs.

I do not think it is legitimate to say that asking for justification for a position is belittling.
