Well, I have been using EdgeMax routers for the past 7 years or so (from the day that the ER-3 Lite was released). I use dhcpv6-pd with them and I think the config is pretty solid. I would do it very similar, if not the same.
It is very close to what @gadams proposed (see above), where the dhcpv6-pd option is added under the interface that gets the delegated prefix. Then, that prefix can be advertised on other interfaces. Important is the possibility to subdivide an assigned prefix into various subnets on different interfaces (using the sla-id option). I think it makes sense to put the dhcpv6-pd under the interfaces, just like normal address assignment falls under an interface. Moreover, dhcpv6-pd and normal IPv6 address assignment can be combined (an IPv6 interface can get a prefix and an address at the same time).
For me personally, I was hoping to start using vyos for my routing/firewall. But without PD it is unusable for me. The alternatives (pfsense, untange, Mikrotik CHR) all have their limitations too. For vyos this feature would be a huge gain.

Thanks for your help!
I'm using VyOS 1.2.0-beta1 (lithium) with a 1 GB HDD on ESXi.
Can I set the number of old instances to keep?
One of my VMs ran out of space because of logs... So how much storage maximum do logs need?
