What does it matter if it affects you're crit fuel at an ETP ? There are a multitude of reasons why you may end up with less than crit fuel at your ETP. It happens regularly particularly in New York if your number 40 for departure.
This is fuel for DISPATCH with the requirment ending at "the commencement of flight". ETOPS entry points etc are irrelevant.
As long as you are confident you can still arrive at destination with the legally required reserve and the required ETOP's technical equipment is still servicable then carry on. The extra ETP fuel is to cover the worst failure at the worst point on the route at dispatch. Once airborne this is not controlling as the statistical chance of it happening at that point are remote to say the least.
Now if you dispatch with an IDG u/s then you would require extra fuel (the APU usage will burn more fuel) but you didnt ask that.
