I think the disconnect here is that people are thinking the routers

... and once the delegating routers are relaying DHCP-PD requests, they
can also relay DHCP address-lease requests to the DHCP server in the CPE
router. This puts all the information about DHCP leases and associated
names in one place, and greatly simplifies the naming problem.
This really falls apart when I'm using 2 ISPs with 2 exit routers.
a-k-a, "Where's up?"
and be put back together by noting that 2 exit routers doesn't have to
mean 2 DHCPv6 servers. A single DHCP server can take PDs from 2 or more
upstream ISPs. If the problem is that exit routers come with DHCPv6
servers, then adding the ability to disable all but one (automatically
or manually) would be worth considering.
