Why used DHCPv6 when RA has RDNSS and DNSSL?

I've said it on IETF discussions and will happily say it again - this
is a particular corner-case that might benefit developers running stacks
of VMs in VMs on their laptops, but I fail to see a real world argument
why this would be beneficial.

OTOH the cost to implement this on the network-side is significant.

Think "enterprise networks".  You have LANs, and members of those
networks.  Not "distribution machinery for arbitrary prefixes to be
doled out in places where you have no idea how many subnets of which
size you might need".

DHCPv6-PD has it's place in "connecting a client *network* to an 
internet provider (wired/wireless/LTE/whatever)" but I totally fail 
to see a positive benefit/cost analysis for anything else.

Even IETF discontinued recommending DHCPv6-PD for "inside a home network",
because it doesn't work.
