True, but that would also apply to encountering Windshear before Vr, and making a "Go" decision.
The Vr for ATOW is bugged. How to handle the different speeds in practice isn't specified, so is a matter to be briefed.
A common practice is to call "Vr" at ATOW Vr, them " Rotate" at the increased speed.
