IPv6 PA prefixes result in that awkward renumbering.  Avoiding the
renumbering implies provider independent network prefix.

With IPv4, you would have typically keept your IPv4 network address
(the old class A, B & C from early 199x) even when changing network
providers.

I've been told that ISPs don't like routing to their customers using
routing-independent prefixes (in IPv4), and that the result is that
small organizations (in practice) use provider address space.
Certainly there would be a problem with routing table size if all
organizations used provider-independent prefixes.
