This relates to the desire to amend RFC7084 to support "southbound"
DHCPv6-PD:

Router cascade with DHCPv6-PD

With routers connected in a cascade, the internal network can be divided into
several zones. This is useful, for example, in shared apartments that want to
share an Internet connection, but each resident should still have their own
(W)LAN. To do this, the front router, which is directly connected to the
Internet, must pass on part of the prefix it received from the provider
(DHCPv6-PD, prefix delegation) and its DHCPv6 server must ideally be able to
use DHCPv6 reconfigure. Only AVM and Wavlink offered both in the test field.
