The use case I'm thinking of is that the application may want to handle this key event differently. For example, the application may want to display the volume differently (visually) to suit its interface. If wm takes away the event, the application would have to poll and display the volume. The UI may become less responsive this way. Since it's the way right now, I'll have to come up with an alternative. However, it's still quite surprising to me that the application cannot register a callback handler of the key events to the wm.
