And then next you can say ok, so /32 bits is big enough for your home, so let's change it again, kill autoconfiguration, ask existing IPv6 users to redo their addressing plans, renumber, etc., and use all the rest of the bits for routing ? And so on, of course, where is the limit ? You should propose this to 6man at the IETF. You're not getting it. Autoconfiguration is a very good feature. More bits for the user to subnet means more business for smart ISPs who don't want to sell addresses but instead services and applications much more easier to deploy thanks to a uniform /48 ways to address all end sites.

Well, wouldn't it be better if the provider simply issued enough space to make NAT66 unnecessary?
The thing is, IPv6 is 128 bits of address space, so a /64 for your home *really* should be enough to have >1 machine online at a time.
It'll be a lot easier to change the subnetting rules inside small networks, and we all know that DHCPv6 is far superior to SAA for almost all cases, but especially home users who need things like their DNS entries set up for them by their "router".
