The ONLY benefit that I can see.
'Bloggs, In the event of an RTO I shall close the thrust levers, apply reverse and roll to a stop over a few KM keeping the brakes cool for another go...'
Back to the real world, where RVR's play a part with rollout guidance (curved localiser anyone?)
One real issue is the engine failure case... Which part of the runway are you gonna lift from? And will you have a headwind or tailwind by that point? Interesting point if the runway is constrained by a little terrain in certain directions!
