I do understand *that*, and I can see that if you do multi-level DHCPv6-PD,
the first router might want to give the second router a /60, so that
this one has 16 /64s for all of its LANs (and so on).
But you'd then normally not configure the /60 onto a LAN segment in between,
but have a /64 between router A and router B, and the /60 routed across
that...
