That's slightly more convenient but I don't see how it is more secure. With one key that has backups if I lose that key I can use one of the backups to disable that key. Multiple keys is slightly more convenient in that scenario because with multiple keys I just have to disable the key that was lost, and then make a new key for the device that held that key and install it. With one key on multiple devices I'll have to install the new key on all of them.
