Well for me mostly because you were concerned with engine rpm above idle which indicates to me that youre in a gear and maybe lugging engine which was another concern. If you're coasting with the engine disengaged, it won't lug, no major power demands.

Since the just above idle loading practices are rare in typical operation, there is no pressure on designers to remediate odd behaviors with lower gearing and most systems tolerate driveline low rpm slippage to increase rpm and torque
