Frankly speaking, getting closer to V1 should not require more thought processing from the pilots. As an FO my job is to call out any failures. And I expect that my CP acts according to SOP. If close to V1 and the config warning sounds and it is "not neccesarily a cause to reject the take-off", who shall check the STAB/FLAPS/PARK BRAKE/SPEED BRAKE? My point being, I simply cannot see that there is enough time available to assess the situation.
