Least amount of back-and-forth between the developer and the admin ("sorry, your key has to be at least 2048 bits", "you forgot to sign your mail", "sorry, I sent you guys the wrong key"), plus it helps assure it's a dedicated SSH key and isn't shared between many other projects and therefore copied across workstations. Mostly, though, it reduces hassle.
