Depends -- the DHCP model also ceases to work, and some time later,
when there's no cause and effect.
When I've added a misconfigured router to my IPv6 network, I added a
few prefixes, but since it never worked, it never got used.
Multihoming and good address selection seems to be a real win there.
Good router authentication would be a nice thing to have in both
cases, though.
