I would suggest that if any of the alternative approaches you suggest is desired, then the best course of action is to adopt this policy as is and submit a new policy proposal as you suggest for the next policy cycle.

> One such alternate approach could be to redefine critical infrastructure such that it is base on a objective standard of dependency by other systems and processes and not simply based on the fact that some word or string has been designated a TLD.  In other-words a TLD should only be considered critical infrastructure if it meets some threshold of dependency by other systems and processes, and not merely based on its location in the DNS hierarchy.
> If a properly objective measure of dependency by other systems and processes could be found, it may also be reasonable to allow other parts of the DNS hierarchy, meeting this objective measure, to qualify as critical infrastructure as well.  Today, there are many large scale domain providers or even sufficiently critical individual domain names that are arguably as critical, or more, to the global Internet as many of the more obscure ccTLDs.  However, with the current definition being based solely on location in the DNS hierarchy, these other parts of the DNS hierarchy do not qualify as critical infrastructure in ARIN policy.
> I have no doubt that some of the new gTLDs may eventually rise to an objective level of criticality that truly justifies the term critical infrastructure.  However, it seems fairly obvious that the vast majority of the several thousand gTLDs being considered will never meet such a standard and should not be considered any more critical than most other parts of the DNS hierarchy.

Then focus our policy efforts on finding an "objective measure of dependency by other systems and processes" that all TLDs, and possibly other parts of the DNS hierarchy need to meet in order to justify being considered critical infrastructure and receiving preferential access to Internet Number Resources.

The policy below is preferable to having the proposed new gTLDs potentially consume large amounts of IPv4 address space, exhausting the reservation and essentially preventing LXPs and other current critical infrastructure from have access to IPv4 resources as intended by the reservation created in ARIN-2011-4.
