Keep in mind that if the cable is stronger, a strong yank will be more likely to break the next weak thing, which might be the USB port of whatever device you are using. I've seen phones where the micro-USB port was just held on by the solder pads, with no special strengthening or through-hole mounting.
Since the device is likely more expensive than the cable, this might not be desireable.
