One of the shiboleths in aviation training is that before V1, thou shalt stop, and after V1, thou shalt go for an abnormality.
How would you judge someone who aborts a takeoff between V1 and Vr with X amount of runway left (X=more than enough required to stop) if they spotted a flock of birds on the centre line capable of doing a Sullenberger on them.
I think the answer to your comment can be found in the preface to the Boeing 737 Flight Crew Training Manual which states:
"Conditions beyond the control of the flight crew may preclude following a maneuver exactly. The maneuvers are not intended to replace good judgement."
For an example of this, study the actions of the captain of an Emerald Airways HS 748 that experienced a catastrophic failure of No 2 engine after rotation. He made the instant and ultimately correct decision to abort the takeoff not only beyond V1 but also after VR.
