Not knowing all the details, it is difficult for me to judge, however it is worth observing that provider independent 
addresses, regardless of where they come from or whether they are IPv4 or IPv6 simply do not scale.  In the face of 
everybody and their mother now being able to obtain PI prefixes from all the RIRs, any ISP that handles full routing is 
going to have to hope their router vendor of choice can keep buying more/bigger CAMs (passing the expense on to the ISP 
who will pass it on to their customers) and/or they'll start implementing the same sort of prefix length limitations 
that we saw back in the mid-90s.

And, of course, we have IPv4 runout in the near future with the inevitable market which will almost certainly promote 
the use of longer prefixes.

In other words, get used to it.
