No I think the GP meant the port on the iPhone as the “other end”. In other words, why not have all of the protection logic built into the phone?

just as an example, imagine you end up putting a fuse in the cable. If the fuse blows, then the cable can be easily replaced. A chip in the iPhone.... not so much.
Though likely there's something in the phone _as well_ as the cable.

If the cable is dumb, it can’t switch the +5v power coming from a USB supply. If it can switch it, it’s not dumb.
