Have broken 6to4 relays is *good* for the long term health of the

for applications. It really isn't any harder in most cases to do
this right.
Not that I disagree with the idea that applications should be able to fail over
from one address to another, but ... why do you assume that the server is
multihomed?
The problem with the broken 6to4 relay on an anycast address is that the
application (or user, or site) doesn't get to choose a different relay.
