Should consideration be given to the non application of reverse power in a STOP situation where it is obvious the a/c will stop on the paved surface. I suspect the 777 incident burnt at the wing root because of hot deflected gases from the reverse system
Modern thrust reversers only reverse the bypass air, not the core flow. i.e. cold air that has not been used in combustion. This was not the case on the v low bypass 737 engine at MAN.
