Apple avoided this by making it an "intelligent" port. There is a bit of handshake that occurs when connecting the magport charger. Until this handshake happens, the power does not turn on. When first connected the LED turns amber to indicate the connection has been made, but the electrons are not yet flowing. Once the handshake occurs, the electrons start flowing and the LED turns green.
That would be kind of pointless though, wouldn't it? The handshake only takes place after the cable has been physically connected to the port. You would need to manually guide the connector to where it needs to be and then keep it stationary until the handshake is ready (which might not be a very long time in human terms, of course).
The part I liked about the magnetic connection was that yanking the cable wasnt catastrophic. The secondary benefit was that the connector had basically zero depth.
