I understand now that you were referring strictly to filter limits- I 
misinterpreted you original post. My apologies.

Obviously you don't need to accept /48's from anywhere- you can restrict 
it to the PI pool- then /32's don't deaggregate but networks approved by 
ARIN or RIPE or whomever still work.

If we start giving out /32's to work around filters I'm not sure that 
solves any problems :) And if no one is going to honor a /48 then why 
bother to give them out?
