I don't object to Option 1 either, and I think the standard has
to be made clearer on exactly what needs to be done.

My only concern would be whether or not there needs to be 
a requirement to defend LINKLOCAL::SUFFIX when configuring

Otherwise, a configuring 'old DIID' node may not detect a collision
with an existing '2462-bis DAD' node, since the former will only
check the Link Local and the latter might not be defending that.

(I'm thinking here of nodes which use RFC3041-like random
or SEND-CGA-like hash generated addresses)
