So? No one is arguing against complete DHCP implementation. I'm arguing
for RDNSS implementation. They are not mutually exclusive.

And they can have it with DHCP. What's wrong with making RDNSS available
to the environments that want it?

I completely disagree here. There are many environments where 99%
of the desktop users just need an address, DNS servers, and a default
route. In a lot of those environments, the guy running DNS is the same
guy running the routers. SLAAC+RDNSS is useful in those environments.
How did this become anti-DHCP? Nobody here was saying turn off
DHCP or don't do DHCP or anything like that. The point was the desire
to have RDNSS support for SLAAC.
Why is it that the DHCP-heads can't understand that pro-SLAAC is not
I say implement it all and let each environment pick the solution that works
best for them.
