As usual an excellent investigation and report.
I sense three areas that might elicit discussion on this board since no design changes are anticipated to eliminate this type of failure.
The continued possibility that fuel contamination may occur in the future if the fueling recommendations are not adhered to.
The minimal actions that the crew may employ in some phases of flight if the contamination should cause a sudden onset of engine control problems.
The mechanism on how this type of contamination affects engine control systems.
The last item is probably only suitable in a tech forum.
