With 10 speed chains, you could technically "re-pin" with their special pin.
Those are also rivet chains. The only exception was 8 speed Campy and Sachs that used 7 speed chains. But Shimano has been insisting on a special replacement pin since 1989 Dura Ace 7402.
Quick links are just a nicer replacement for special pins.
