Hi,
Perfect match is faster but far from better. What I think perhaps would be 
interesting to see in the future with regards to IPv6 and PI is the 
following:

1. No PI. _Only_ network operators get a prefix.
2. Customers of network operators can at any time change provider and take 
their assigned prefix with them. The new provider will announce it as a more 
specific overriding the aggregate. If the customer decides to get multiple 
providers, then the network operator with the /32 could also announce a more 
specific.

In the country I live in I can change telecom provider and take my phone 
number with me to the new provider. Why shouldn't I be able to do that with 
internet providers?
Yes, it will somehow create millions/billions of prefixes (atleasat with 
todays routing technology/protocols). Network operators should be able to 
handle that hence rule #1.
