One reason IPv6 addresses are 128 bits long instead of 40, 48, 64 or 80 is because converting from IPv4 to IPv6 is really painful and we don't want to ever have to do it again in the future.
Sure, 128 bits I can see the point of. Rigid insistence on /64 subnets when no broadcast domain will ever have 2^64 devices on it seems like a less obvious choice. - Mark
