I work with a lot of enterprises on large-scale DHCP. It's actually
pretty common for them to want many more options set than just what the
resolving name servers are.

The other issue that comes up often in these discussions is the idea of
administrative separation between the people who run the routers, and
the people who handle things like DNS and DHCP. Most enterprises want
this separation preserved.

SLAAC was an interesting idea for the simple provisioning of dumb
devices. Anything more exciting requires DHCP. It's very unfortunate
that the anti-DHCP contingent is still fighting a battle that they lost
12 years ago, and delaying wider IPv6 rollout as a result.
