I wonder how much blanketing (slowing down of the air) of the tail would happen with a windmilling propeller. A wind powered propeller has the bottom of the airfoil facing the airflow and is around 30% efficient (50% theoretical). An airplane propeller would be less efficiency so not a huge effect but significant for planes where the propeller is close to the tail but less so for a conventional planes. The above assumes the efficiency of the propeller is proportional to the reduced air velocity (effective).
