Well, your wrong, it wasnt inspired by a mod... (Not to mean it wont be just a s bloody awesome as that mod, but it doesnt mean that the mod "inspired" them to change the archery system, they most likely did it on there own...)
"Compared to Morrowind and Oblivion, Skyrim’s bows are increasingly differentiated from melee choices. Bethesda took inspiration from a popular community mod by turning up arrow damage but making ammunition scarce. Players may only have one shot, but if it lands, the result is devastating, increasing the role of stealth in the archer’s skill set."
