The way around it is to stop growing the DFZ routing table by the size of the Prefixes. If customers could have PI addreses and the DFZ routing table was based, instead, on ASNs in such a way that customers could use their upstream's ASNs and not need their own, then, provider switch would be a change to the PI->ASN mapping and not affect the DFZ table at all.
