Without the pressure from operators assigned out of new space no action would take place. If it was possible to return a block for a new one, there's only so much address space that a RIR could possibly hand out, we'll still come back to the problem of routing new blocks. Kris

The returning ICMP packets may take many different paths back to the sender of the UDPs, since each hop will make it's own decision on how to return to the source (not just the single asymmetric path from the destination of the UDPs).

Not knowing how much damage would result from 500kg of explosives.. What is the typical size of pipe a carrier would pull into an interconnect facility, how many carriers, how much traffic? Now how much traffic would shift to other facilities if one went down? How many would it take to saturate the pipes? And at what point would congestion be bad enough to render them useless? At some point traffic will shift over to private interconnects either through complete loss of peering in third party facilities, or through manual intervention. Kris

You should be able to filter. RADB is one solution that may make it more manageable. But if your not filtering it will still require a transit provider to get the traffic back to X (think asymmetry).
