Uncontained engine failures are always considered to be potentially catastrophic independent of any ETOPS considerations (recall the close call from the uncontained turbine burst on the Qantas A380, and it still had 3 engines running).
So the focus will be on what caused the uncontained failure, and how to prevent a future occurrence.
