immediately with a /56 and I haven't touched it since. I have been using it
to SSH back home quite comfortably with an almost unmodified ACLset to
permit port 22 inbound.

This is on Internode, in Australia.

It just worked.

And it should "just work" if you have two router daisy chained.  PD
was designed to allow this to work.  The home router vendors had
all the protocols required to make it work.  They choose not to
implement a working solution.

It isn't that hard to supply a take a PD request on one interface
and make a upstream request if you don't have unassigned space to
hand out then return the response add routing table entries to keep
it all working.

One can do more complicated stuff than that like running a routing
protocol but static routes also work.  It may not be optimal but
there was nothing stopping those other vendors from coding the
support.

Most home routers already do stuff like that in IPv4 for DNS servers
and other protocol elements.  They take what they have learnt from
upstream as supply it downstream.

I'm curious, do you know of a consumer-grade router which supports
DHCPv6-PD?

I have tested a whole bunch of them more than a year ago. I can remember
seeing IPv6 DHCPv6-PD client support on gear from AVM Fritz!box, D-Link,
Draytek, Zyxel, Linksys, Asus, Thompson/Technicolor and I must be
forgetting a few as well. Most of them weren't very advanced, but they
worked to get IPv6 connectivity in the house. What I am missing these
days is DHCPv6-PD server support to re-delegate parts of the prefix it
got from the ISP downstream to other home routers. As far as I know AVM
Fritz!box is the only one that does that today.

And the need for it was obvious when all the other boxes were being
developed.  Daisy chaining routers has been part of home setups for
many, many years if only to get configuration control because the
ISP router is not configurable enough.  There was no reason to think
that this would change with IPv6.

Cheers,
Sander
