Ironic that you'd bring up the A380 and QF32 when talking ETOPS. I'm reasonably sure the A380 has four engines and as noted, that really didn't help.
A big part of the statistical argument for ETOPS is that - given today's engine reliability - having more than two engines doesn't improve safety because more engines means a greater probability of a catastrophic engine failure that endangers continued safe flight and landing (e.g. uncontained failure or uncontrollable fire). QF32 was a result of an uncontained engine failure - and since it has four engines it's twice as likely to experience an uncontained engine failure than a big twin.
