Now that you have said "there's no correct use" you have managed to 
logic yourself into silly-land.

That is utterly specious logic when duplicate WWNs are quite unlikely, 
and furthermore -- as demonstrated by use in network drivers -- use of 
the feature itself is not the common case.

Field experience directly contradicts this entire line of reasoning.
