One issue I know of (part of the findings in the G650 test crash) is that a rapid rotation can cause the plane to be airborne in ground effect and the rapid rotation can slow acceleration. Where a slower rotation rate results in the plane passing thru ground effect and accelerating. A wing stalls at a lower AoA in ground effect than in a free stream. so, the wing can rapidly reach its stall AoA in ground effect and roll off.
