The assumption that the router "knows" it is correct for every host on a given LAN simply does not map to reality deployed today.
What I'm saying is that a router knows whether it's a router or not. A DHCP server does not, so it has to make a leap of faith and then sometimes the hosts fall flat on their face if there's no router on the address indicated by the DHCP server. The counter-argument is "it works today" but my counter-counter-argument is "it doesn't work today". I get burned by broken DHCP setups _all_ _the_ _time_ at work, at IETF meetings, at RIPE meetings, etc. Anyone claiming that having a DHCP server direct hosts to a router address in the blind is simply incompetetent, so there is no point in listening to them. If, on the other hand, the REAL desire is to have a DHCP server break the tie in the selection between several routers that advertise their presence, that wouldn't be unreasonable.
Please explain to me how I can achieve this functionality in RA/SLAAC or stop pushing to prevent it from being available in DHCPv6.
There is no requirement that the IETF provides all functionality that someone can think up. The list of desired functionality is infinite, and much on that list is a bad idea and/or can be achieved in different ways.
Seriously, we're all adults. So treating us like children and taking away the power tools is not appreciated.
Stop trying to break the internet and I'll treat you like an adult.
