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
Problem is defining/appreciating in the heat of the moment "where it is obvious the a/c will stop on the paved surface.......", a rejected take-off is not really a manoeuvre where's there's a lot of time for analysis or finessing (IMHO because in the simulator that's been my experience but then again I'm a bear with a small brain)
If it helps though there's already a caveat in the 777 procedure that for the rejected take-off manoeuvre it's reverse idle only at lower speeds (possibly operator defined).
