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.
And I'd argue the FO as PF already has their feet on the pedals, and maintaining centerline is just as important. I would even argue transfer of pedals is more of a risk than transfer of who has the thrust levers.
Also, how is an RTO is any different than a balked landing or a very low altitude go around? Both maneuvers require quick decision making and action in an area of high vulnerability. Yet, the FO is perfectly capable of calling and performing both maneuvers.
