For what it's worth, I heard that ETOPS-wise only in flight shut-downs on ETOPS sectors influence the statistics that might reduce the overall fleet ETOPS status.
That's why they always tell you NOT to shut down the engine, at least not in the ETOPS sector.
In the BOM-T7 case it seems typical: Maint gets notice of a deteriorating engine status, tells crew there's no problem (!!), to continue and to monitor the parameters, as shutting down now would have an impact.
Later on the engine starts getting the ****ters and the crew has to go emergency, but it's no longer in the ETOPS frame, so no one no longer cares .... the stats are satisfied, Maint did what they were supposed to do and the crew can now be blamed for not having shut down earlier ....
Might not be the exact case here, but you might get the drift.
