Well thats not completely true. Plenty of softer compounds than A6 on non DOT race tires however its still very soft and its operating tempreture range is much lower than most race slick compounds.
Remember that DOT R's were born from "cheater slicks" People would buy race slicks and put groves in them to run on the street. About the only differnce between Race slick and DOT R slick is fact that tire has DOT approval which means it has minimum contruction to pass DOT standards and has minimum tread groves to satisfy the DOT regulations. All the suppliers of slick type DOT R tires say for racing only now. DOT R's are very close in construction to regular radial race slicks they are just use a little heavier construction and belt to meet DOT requirements. Tire compounds and construction used in true race slicks tend to be more tolerant of heat as well.
But truely tires like A6 are race slicks by defintion. They are made for racing and they are slicks. Many people use A6 and R6 as they would a radial race slick. In some situations A6 is faster than a non dot slick.
