Without speaking for or against the policy, I'd like to point out that there definitely are cases where unique addresses are required, despite not announcing the route to all of autonomous systems. There are plenty of RFCs explaining why. It should also be obvious that even if 50 /8s were recovered they would not be enough to meet demand. There are about 7 billion people on Earth and more than half do not yet have Internet access. IPv4 is not a sustainable resource.
