+1 Good text. Yes, it's much clearer now, and also answers my question
of what DHCPv6 content service providers would want to serve to client
end nodes on the customer's LAN. ;)
Thanks

Subject: Node Requirements: Revised text for DHCP on routers
Message-ID:<[email protected]>
Going through this thread, here is some proposed text. I've concluded
that whether to require DHC and/or relay agents is much more nuances
than a simple SHOULD/MAY/MUST.
How about the following proposed wording:
12.3. Stateful Address Autoconfiguration (DHCPv6) - RFC 3315
A single DHCP server ([RFC3315] or[RFC4862]) can provide
configuration information to devices directly attached to a shared
link, as well as to devices located elsewhere within a site.
Communication between a client and a DHCP server located on different
links requires the use of DHCP relay agents on routers.
In simple deployments, consisting of a single router and either a
single LAN, or multiple LANs attached to the single router, together
with a WAN connection, a DHCP server embedded within the router has
been a common deployment scenario (e.g., [RFC6204]). However, there
is no need for relay agents in such scenarios.
In more complex deployment scenarios, such as within enterprise or
service provider networks, the use of DHCP requires some level of
configuration, in order to configure relay agents, DHCP servers, etc.
In such environments, the DHCP server might even be run on a
traditional server, rather than as part of a router.
Because of the wide range of deployment scenarios, support for DHCP
server on routers is optional. However, routers targetted for
deployment within more complex scenarios (as described above) SHOULD
support relay agent functionality. Note that "Basic Requirements for
IPv6 Customer Edge Routers" [RFC6204] requires implementation of a
DHCPv6 function in IPv6 CE routers.
