So you accelerated the runout by ?? ~ 3 minutes... is it really worth the

Seriously, APnic alone is burning 5% of a /8 per day, and collectively all
the RIRs have burned through 7.7% per day for this calendar year. In any
case, it has been argued both ways that a larger pool will accelerate &/or
slow the eventual ARIN exhaust date. There are simply too many unknowns to
call that right. The only way to avoid this mess is to rewind the clock 5
years and start IPv6 deployments in time to make this step unnecessary.
Since we don't seem to have anyone stepping forward with an operating time
machine, that doesn't appear to be a viable option...
