I doubt they can afford to fab chips for so many different algorithms right now. They also made the mistake of not decoupling the algorithms on their X11 chips - they can be used for X11 only, and not any algorithm built from the same components. Look at Baikal and now PinIdea/DaYun X11 miners - they are also capable of hashing algorithms using different combinations of the X11 algorithms.
but if these are coming off their shelf from their active use; they aren't impacting the overall algo sum net hashrates as if they are a new product. You probably aren't considering this.
Their impact is minor considering the SPx36 units coming online, literally 31x the hashrate per unit.
