Actually, they probably would have stuck to a 64 bit address space and 
it was debated. Then it came down to, let's make it a 64 bit network 
space, and give another 64 bits for hosts (96 bits probably would have 
worked, but someone apparently feels the next bump from 64bit is 128bit 
so there we go).

Renumbering, when the system works is a breeze. Of course there are a 
billion places where autoconfiguration doesn't work well, and those will 
still require effort to renumber.

At least with this method, if Cisco supports DHCPv6 IA_TA option and 
proxy-nd similar to how they support IPv4, then a single pool will 
handle an entire pop no matter what. I'm sure 32bit host addressing 
would have been fine too, but then we're stuck with that 96bit value 
that no one likes.
