A million addresses is 1/16th of one OUI in EUI-48, and there are
4,194,304 OUIs (after you take out the local/global and
multicast/unicast bits). Billions or even trillions of addresses are
manageable without needing EUI-64; millions is a drop in the bucket.
Still, it's good to know that another link layer -- which people _will_
be running large IPv6 networks on -- is using EUI-64 and that it's not
just a FireWire thing.
