In the case of xDSL, using bridged ATM encapsulation is enough, you don't 
need to worry about IPv4-only properties of CPE.

I don't think anyone has suggested that we don't try to find some 
solutions which enable these users, too, to get IPv6 connectivity.

It seems some design teams move faster than others: unmanaged networks 
team IMO was already working on solutions.  At this point, until we know 
the problem space better, I think it's best to assume "don't try to solve 
every possible problem unless shown otherwise" -stance.
