I would expect suppressors would mitigate the rise of the peak overpressure wave, unlike the muzzle brakes that prone supported 50 cals have sported since forever. Would kick your boots around if you had splayed your legs a lot in the prone position.
Certainly, for other high impulse weapons (like the Carl Gustoff) there is a peacetime limit on the number of rounds you can fire daily. Its less than a hand full from memory.
