>here are no such margins in the V1 stop/go part of the equation,
What about the "reaction times", the use of Thrust reversers and accounting for worn brakes, arent these margins?

Trouble is that if you attempt to count reaction times as margin for success, just as many times it will be a margin against success given that it also increases pilot error rate in doing the wrong thing by a quick reaction. "trained reflex" is more like what is needed but, to accomodate all pilots the training needs to consider typical reaction times.
The same kind of argument can be made about reversers. Seeing as how many aborts involve yaw and or perceieved engine failure, you start to get problems with the pilot grabbing a handful of throttles and than trying to dither the correct ones to aid in activating just the right combinations of reverse thrust. This is relatively easy when you have lots of time (landing) but might not be the first thing you are going to do in the first 5 seconds of a high speed stop with yaw.
Your mileage may vary, so I'll await and see if anybody has actual experience with this on the forum. All mine has been negative
