I think it is unlikely for USB cables to be easier for the average person to repair without tools like pliers, a soldering iron, and magnify glass.
But, it would be nice if the USB cable's wires, plugs, and ports are easier to repair or replace by unscrewing the damage part, and replacing the broken USB plug or wires with a working plug or wires instead of throwing away an entire cable because the plug or wire got damaged.
