Hi, Nick:

1)    " ... So that suggests that 240/4 would provide a little more than 1Y of consumption, ...   ":

    EzIP proposes to use 240/4 CG-NAT's 100.64/10. So, 240/4 will be reusable worldwide and no need to consider consumption rate.

Reclassifying this space, would add 10+ years onto the free pool for each RIR

on this point: prior to RIR depletion, the annual global run-rate on /8s measured by IANA was ~13 per annum. So that suggests that 240/4 would provide a little more than 1Y of consumption, assuming no demand back-pressure, which seems an unlikely assumption.
