Though lightning had 8 pins, for being reversible it is actually 2 pairs of 4 pins.
USB-C works around this by using cc1/2 pin which indicates the orientation of the connection.
I think the Lightning-Protocol was a little more difficult, because there were Display Adapters which probably need more than 4 lanes. And who could forget: some iPad actually had Usb 3 over Lightning.
