And you still need to have a strategy to deal with collisions.  You
also need to be able to communicate the resulting address to all
components that need to know it.

I still see no benefit between picking a random block in 1::/32 vs
picking a random block in fd00::/8.  In both cases you have to deal
with collisions.
