Robin,
Short version: Renumbering of end-user networks can never be sufficiently testable, reliable or secure to be in any sense "routine".Therefore, we cannot expect to have a routing scaling solution which depends on such "routine" renumbering be accepted by the vast majority of end-user network administrators - which is a requirement, since we need to get almost all such networks to adopt it.
I regret that I do not have time these days to read through more than your short version, but I generally agree with your design assumption. This is not to say that I don't hope for better. DHCP prefix delegation is a good step in the right direction, particularly for SMB & home networks. I've consistently said that our scaling problem is NOT with enterprise networks, but with home and personal networks. In those latter two cases I hold out more hope. If enterprise networks were merely a 2^6 exception, we would be in good shape.
