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.
