As far as I know Airbus has also produced an interesting video when it comes to the importance of abandoning t-off at or below V1. It was very interesting to watch and the reason it was being produced , was to make pilots to be go minded above 100 kts (i.e. even below V1). It was by no means produced to abolish the term V1, but just to make pilots think twice for abondoning t-offs above 100 kts. It will be very interesting if you have the opportunity to watch this video.
