Not true.
Some would like to use DHCPv6 to hand a host things like DNS servers,
NTP servers, PXE boot information, domain name search paths, and
the like. There's no reason once the host gets a DHCP address and
that information it can't also generate and use a privacy address
or CGA.
While this thread has focused on folks who want to use DHCPv6 to
preclude these items by for instance having switches and routers
filtered to only the "allowed" address (assigned via DHCP) there's
no requirement a network operator do that.
DHCP has a couple of hundred defined options. Vendors have tried
adding ONE to the RA protocol (DNS servers) as replacement
functionality. That leaves them a few hundred options short, in
my book.
