I'm not saying that we should give every device a /64 using DHCP-PD. SLAAC is
probably a much better way to distribute addresses locally (at least as long
as we don't mess up IIDs completely).

But, the addressing architecture does allow for one /64 per device. So when
needed, it is better to use that space than to add all kinds of complexity 
while trying to save a few bits.
