The protocol was done in December 2003.  Any CPE vendor could have
added support anytime in the last 7 years.  Did we really need to
specify how to daisy chain PD requests when these vendors have been
daisy chaining DHCPv4 for various option without any written
specification?

People have been begging the CPE vendors for IPv6 support for years.

Seriously.  CPE vendors could have release IPv6 capable products
that had a stateful firewall, DHCPv6 with prefix delegation 7 years
ago.  There was *nothing* stopping them except themselves.

People have been retrofitting CPE devices to have this functionality
for about as long as this.
