Re: [v6ops] Continuing WGLC: ietf-v6ops-dhcp-pd-per-device-03

Hi Jen,

I would put myself in an obstain position on the WGLC voting.
From one point of view, it is already a good step in the extension of use cases footprint:
"Note that assigning a prefix of sufficient size to support SLAAC does not require that subtended nodes use SLAAC; they can use other address assignment mechanisms as well."
But from another point of view, section 8 makes a good attempt to motivate that "never-ever longer than/64 for sub-delegation because SLAAC may be behind".
DHCPv6 or Local Algorithm (for Container) may be behind then /64 is not mandatory at all.
Fortunately, the current text does not block such an opportunity.

Draft readability has become very good.

You have lost the comment from Ole: "Why Broadcast network? Any special meaning?".
I propose to delete "Broadcast" in the draft title.
Subnet could be small but the document may be applicable anyway. It is up to the network owner.

If you preserve "broadcast network", it is better to replace it with "broadcast subnet".
Because "Broadcast network" is something different: https://en.wikipedia.org/wiki/Broadcast_network
