From my perspective
There seems to be some parsing going on. No axe here, the Fuel/Powerplant interface certainly must be rigorously examined. Boeing built a freestanding Tank/Supply mock-up/test-bed, and then concluded that the Trent has issues. Can the Plumbing be re-designed to accomodate the Trent's shortcomings? Add fine screen filters and robust bypass systems, and fuel pre-heat? For good measure refit PW and GE equipped frames so the Trent doesn't feel picked on? I may be missing something, it wouldn't be the first time or the last; Isolating the architecture of the RR F/OHE for criticism appears to be Boeing's conclusion.
