If there was evidence that there was a design problem with the engine, it would impact ETOPS. Cathay ended up ceasing ETOPS operation (and in fact grounding their A330's) after a series of incidents with the Trents that were clearly design related. The problem with the GE90 has been identified by various sources as a on of assembly error in the engine.
