If there’s truly no time, which I believe is correct, the person seeing the problem should call the abort and the PF immediately stops the aircraft. No cross cockpit comms issues, no delay in action.
You can’t have it both ways by saying there’s no time to make the call but that there’s plenty of time to have communication, decision making and control transfers.
It's better because the Captain has their hand on the thrust levers, is trained to make that decision, and is the ultimate authority for the safety of the flight.
Also with the Captain's hand on the thrust levers, every takeoff the Captain has at least partial control and can get to the thrust reversers quickest in the event of a high speed abort.
