I am not an authority on performance but I think you need to examine your statement. If aircraft can be controlled with precision below Vs stall wouldn't be such a bugbear. Below is JAR definition.
JAR/FAR 25.149 Minimum control speed
(b) VMC[A] is the calibrated airspeed, at which, when the critical engine is suddenly
made inoperative, it is possible to maintain control of the aeroplane with that engine
still inoperative, and maintain straight flight with an angle of bank of not more than 5
degrees.
(c)VMC[A] may not exceed 1.2 VS with
• Maximum available take-off power or thrust on the engines;
• The most unfavourable centre of gravity;
• The aeroplane trimmed for take-off;
• The maximum sea-level take-off weight
