I agree explosive growth of TLDs is unlikely, and not intended to be
supported by this policy.
There is an intentional limit to the growth supported by this policy, we
are only reserving a /16 for critical infrastructure, and for at most
three years. Once this reservation run out, it is out, and then
recycling of IPv4 will be necessary to fulfill even critical
This policy only intends to support IPv4 critical Internet
infrastructure during a transitional period to a dominate IPv6 Internet,
not an unlimited amount of growth or for an indefinite period.
Finally, I support this policy as written.
