Sparrow Control is the funny meme mode, its probably not meant to be taken seriously, kinda like Bungie and their promises. I have seen people use it for tossing funny things on their sparrows like Anarchy shots or tripmine grenades, I just wonder though, what if you hop on your sparrow and your teammate shoots you with a rocket launcher with Lasting Impression and you speed boost it into a spawn or control-point with the whole enemy team.
