The question of whether DHCP should be used to supplement SLAAC< when
SLAAC is used for address assignment, woudl seem to be a separate
question. In, for example, the SAVI work, we have been told repeatedly
by folks deploying IPv6 that they have to be able to use SLAAC for
address assignment. I have not tried to survey the equipment. Rather,
I am trying to provide the various operators with solutions that meet
their reported needs.
To respond here to one of Doug's comments, if 5% of the hsots can not
use DHCP, then for most operators that would make DHCP address
assignment a non-starter. Having 5% of your customers fail, and
probably consume large amounts of support time figuring out why they
failed, is simply not workable.

Now, operators wanted to offer IPv6 service. I hope we think that is a
good thing. For residential, they looked at what they could count on
from the hosts. And some of them concluded that they could not count on
DHCP, so they designed an architecture around SLAAC. In other words,
they ddi what we told them to do.
On the other hand, some operators have concluded that RA/SLAAC is simply
insufficient. Currently, they need to use RA plus some other mechanism
(for instance DHCP) - but they would *prefer* to use only one mechanism.
Currently, SLAAC/RA alone cannot supply all the necessary parameters
- but people seem to want to put more and more into RA/SLAAC. That
would be fine by me *if* we can also have a full featured DHCP which
can operate without RA. Yes, I know there's strong political/religious
resistance to doing this - but I believe this is where we're headed...
