I'm glad to see that several of the big vendors seem to disagree with
you.
- Cisco does RA as soon as an interface has an IPv6 address, but has a
knob to disable RA (ipv6 nd ra suppress).
- Juniper does *not* do RA as soon as an interface has an IPv6 address,
it must be explicitly configured.
So we are part way there - IPv6 can be used without RA. We just need
DHCPv6 to work properly without RA.
