Sure, and if Curt had quoted two paragraphs about ULAs instead,
I would have pointed out that the user-generated pseudorandom
global ID within them means that they too are unlike local
IPv4 addresses, ie not fundamentally identical.
A consequence of IPv6 ULAs having a global ID is that it should be
straightforward to merge a number of local sites with independently
assigned addresses, without causing any collisions.
Perhaps that clarifies what I took from Curt's use of the term
"fundamentally identical" with respect to IPv4 local addresses.
