Last time I checked, provider-based prefixes were obsolete.

Link local addresses will reduce the number of transfer nets, but
that's about it. Autoconfiguration will even increase the number of
assigned addresses, because the address is generated from the EUI-64
address, wich is 64 bits in size. Any LAN will end up with a /64
network. But that's not a problem, because we have 2^64 of them.

Of course it will work. IPv6 contains intelligent network
renumbering. With IPv6, renumbering will become common practice.
