It can, but using it that way essentially forces you into picking an
"upstream" interface on each router and building a spanning tree that
the assignment travels down on.  It's just running the same protocol
up- & downstream as server and client, not some actual "levels" feature
in the protocol.

Unless I'm misremembering (yeah, long time...) there was consensus that
hierarchical DHCPv6-PD is not desirable for homenet;  if a network
warrants using OSPF or IS-IS, hierarchical PD is going to be even less
desirable.
