Although there is no shortage, I disagree in principle.

While I agree a two-tiered system would probably be best, assuming that
we will never run out if IPv6 addresses is like saying nobody will need
more than 640K.

Nobody knows what the future holds, and being reasonably conservative at
the beginning will only help later.

What happens if someone implements something in the stack that would
allow a device on a network to iterate through a billion addresses
randomly every few minutes, with the ability to notify it's important
peers to be able to avoid security threats? What if every single IP
enabled device on the planet did this?

I don't believe in never say never. As far as passing it to our
descendants, they are going to have enough to deal with in the
environment alone.

I support the previous statement. Clean and easy.
