How prevalent is this problem? There might be not point fixing a problem
with a 0.2% probability of occurring, especially as it might be cheaper to
detect and fix the errors at the application layer.

Could you please explain how broadcast is better than solicited node
multicast. In any case we aren't getting round that for now and it is
deeply imbedded in NDP. I am interested in your negative experiences with
solicited node multicasts.

Just because you can have 2^64 possible hosts on a LAN still doesn't mean
we through principles of good LAN design out the door. :-) So I'd say it's
rather the fault of shoddy network design rather than address policy.
