Several large operators have said, repeatedly, that they want to use
DHCPv6 without RA. I disagree that this is stupid.

We're planning to use DHCPv6 and RA (with no prefixes, only for the
link local next hop). This is more complex than using DHCPv6 alone,
without RA, would be. When and if DHCPv6 without RA is possible, we
certainly plan to turn off RA on our BRAS boxes.
