This change has also a practical reason. When flashing and testing the hardware this change makes it easier to make sure all the LEDs work. Now when the DFU bootloader is idle it is scanning the LEDs making it easy to see if one of them has an issue. In addition to that, the bootloader now indicates when there is data being flashed using the DFU interface. In cases when one has more than one device connected and accidently starts flashing a wrong device this is very useful feature to have.
