In depth

The rule is use, never presence, and that single word is most of the design. A controller plugged in for something else, or left on a desk, must not change every prompt on screen while the player is still on the keyboard — which is the bug this kind of feature usually ships with. The browser helps: it does not report a gamepad at all until a button has been pressed on it. This closes the rest.
