Yes, but they should be ignored, though other than RDNSS, I wouldn't
really want to add anything else and agree that if you need more than
the absolute basics, DHCPv6>SLAAC. The difference being that I
consider RDNSS an absolute basic and some of the zealots in this
argument do not.

Yes, but they should also be ignored.

SLAAC+RDNSS = perfectly functional for 99% of environments, actually.
DHCPv6 = more comfortable for people used to DHCPv4 and more useful in areas where more extensive autoconf information or control
Simple as that, really.
I've used both protocols and feel that they both have places where they excel and places where they are less desirable.
