I care?

A6 can be seen as a generalization of AAAA.  It provides a means within the 
DNS to separate the routing prefix from the endpoint identifier thereby 
providing hooks to simplify renumbering.   I'd consider that a useful 
feature.  However in the trivial case, A6 can be made to work exactly like 
AAAA.  Constrain the depth of the A6 chain or constrain how the delegations 
are done and you can gain whatever level of reliability or usefulness you 
desire.

Are you saying A6 cannot be made as reliable as AAAA?
