We want ISPs to give out /48s to any of their customers who ask for 
one.  A /36 is enough to allocate 4000 /48s, whereas a /40 only gives 
you 256.  IMO /36 could be reasonable for small ISPs, but /40 or smaller 
is too constraining and too likely to get used up.

I understand that ARIN is considering changes to the fee structure 
(https://www.arin.net/fees/fee_schedule.html).  Not sure what they're 
considering, but one option may be to charge less for a /36 than for a 
/32.  Without some way of differentiating small ISPs from medium-sized 
ISPs in the v6 world, it's hard to stick with the 
fees-based-on-block-size model we have now.

Of course, fees aren't policy.
