I hear many comments about "the slippery sloap". And "make them get PI if they want to multihome". However, my customer's dont want PI. Just because one person finds this as an ideal solution does not mean everyone will accept this solution.
Also, a /48 is not a gigantic hole in the filtering opposed to /32. And to open up /48 for PI only is an unbalanced policy. If I had known people would be using PI as an excuse not to let Upstreams multihome with V6 I would have advocated to shut down that policy proposal. I support PI but for poeple to turn around and force feed PI is not acceptable.

I agree. Depending on their configuration/hardware/sales people, some
ISPs may choose to filter at /48 globally, while most will probably go
for /32 except for the /48 PI space. I expect that at some future
date, /48 will be the de facto filter unit. That will depend on the
(slowly growing) availability of routing slots, combined with the
market forces that drive ISPs. Routing best practice is to not do
something that causes massive instability and your customer base to
This is a business problem, not a policy problem.
