Given this behavior, legacy registrants should, for your sake, give up
their underutilized address blocks?

Those route aggregation policies are strictly internal to the Verizon
empire. Your company set them entirely on its own. No technical
limitation prevents you from routing any Verizon address on down to a
/32 anywhere within the empire that is Verizon. Certainly nothing
stops Verizon from moving addresses 20 miles within the same US state.

I'll bet you run the Ashburn data center as a separate AS. It provides
you with the largest obstruction possible against anyone moving out.

The next time folks on this list get to discussing provider
independent address space, I'll pull this post back out. I think it
beautifully illustrates real-world customer abuse which occurs as a
consequence of too much emphasis on provider aggregatable space.

Would you then support a dual fee structure? One for LIRs which change
their service prices based on the number of IP addresses assigned to a
customer and a second for LIRs which don't?
