Well, if you look in Verizon's routing table, you'll find that the following
route is missing from their perspective on the DFZ:


There are many others, as well... Roughly 20% of the IPv6 routing table
seen by other providers and their customers.

The point is that ARIN does not dictate routing policy.  Yes, so far, most
ISPs choose to route most or all of what ARIN registers, but, there is nothing
in ARIN policy compelling them to do so and they are free to change that
decision at any time.
