Assuming the network type is broadcast/multicast capable, yes. In that
case, you'll want to adve

DHCPv6 should not care about *any* routes.

A route learned from an RA will *always* have a link-local next-hop.

This could
get non-trivial when there are multiple routes provided by RA. NM
must then find the route that matches the DHCP6 address to determine
the correct prefix.
An address assigned by DHCPv6 IA_NA is just that, a single address.

Agreed. As it happens, NM recently gained support for such setups.

That's correct, but at the time that bug was filed I did not know enough
about IPv6 configuration to suggest the correct course of action. I now
know much more and realize that adding it back was a mistake. We should
