Gang Sprays and spray radius/size

It seems as if gangs have the ability to purchase unlimited sprays giving a small coverage zone of the map. Some gangs have over 40+ sprays. With the amount of sprays gangs will be endlessly beefing months on end to try and claim a turf. It would be nice to see a limit put on the amount of sprays one gang can have, but increase the radius/zone size it covers. Ballpark 15 sprays per gang double the coverage size/zone.
