I was simply pointing out that, while the fuel load required for an engine failure that depressurizes the airplane is covered by the ETOPS fuel reserve rules, the fuel required if you add drag from a nacelle with a severely damaged or missing inlet is not covered.
Ir was a disk uncontainment along with its blades, quite a bit more robust than a fan blade release. A fan blade release simply doesn't have the energy to make a big hole in a pressurized cabin.
