Many folks would consider that a benefit.  Hosts within an enterprise  
need to be managed in a scalable manner, which effectively  
necessitates the proxy approach.  This is the same driver that makes  
proxy mode for shim6 a pragmatic necessity.   Along with that proxy  
mode, it would seem that this would relieve the burden on the host of  
learning and retaining all of the addresses in its bunch.  This would  
actually simplify deployment.
