They don't scale.

It is 64K prefixes, but I'm unsure why you'd imply there is a limit  
of a single /32.

Why do you assume only folks with ASNs will request PI space?  Why do  
you assume only one PI block per organization?  Why do you assume  
only one route per block? None of these assumptions are true today.
