The only change in the SuperDrive that Apple should consider it to move to having removable cable. That way users can simply select an appropriate cable. Having a micro-USB-B 3.0 connector on the drive would allow any micro-USB cable, either 2.0 or 3.0 versions, to be used and the user would have their choice of a USB-A or USB-C connector on the other end.
There are a number of drives available from other manufacturers that use removable cables. Given that optical disks and floppies and antique tech, these usually are tray loading mechanisms and continue to use the older mini-B connector on the drive. Mini-USB to USB-C cables are readily available, as are min-USB to USB-A. My wife's Toshiba drive works this way and has be fine for the limited use she has for older media.
