Seems from the Emergency AD that my postulated theory may have been at least partially valid:

I do feel for the Service Engineers (and there may be a few Development Engineers out in the field as well by now), who are having to make a call, based on their inspection, as to whether to 'pull' an engine... or not. No-one wants to have an AOG a minute longer than they can avoid, and the reputational consequences, for both Airbus and RR, of lots of WhaleBuses sitting around, are not good... the only thing worse, of course, would be another in-flight emergency.
Good luck, guys. Well, actually, it's not luck, it's experience and skill...
