For me, another important issue to solve is the ND exhaustion when there 
is scanning going on. So for me, the value of this document is if there is 
a "non-discovery mode" of ND implemented. It might be better to do this in 
a different document, I don't know.

So a mode where the clients use ARO to register their addresses, and 
legacy clients use DHCPv6 for IA_NA and the ND table is populated by these 
two mechanisms and packets destined for unknown IPv6 addresses are just 
dropped.

This would be a big win, especially if it could be done with minimal 
changes to the clients.
