I'm not entirely convinced that "every web app should define their own idle timeout" is such desirable behavior that we should build our API around it by forcing every caller to specify their idle timeout - having a standard event that's fired with an exposed state for apps that need it seems like a cleaner approach. The trouble with this is it doesn't allow any experimentation on the part of the app/entity to figure out what is the best idle time for it's purposes. In terms of chat it might be that a 3 minute or 5 minute idle time works best in terms of people's attention. For something like watching a video perhaps a 15 minute idle would be a better length of time, or for an online game a longer idle time is probably useful before being signed out. Different purposes have different requirements for the idle time so it makes sense to allow them to specify the different timeouts. This requirement could be solved in several other ways, f ex making sure that the "standard" timeout period is short enough to not be longer than what any app wants. Then (as was previously suggested) an app that wants a longer timeout can do setTimeout and trigger its own idle stuff if status has not come back to "active" during that time. Another alternative is to have no event, and just a property: window.lastUserActionTime which is kept updated with the "msec since epoch" for the latest user input on the desktop. Then an app can implement its own idle functionality with totally own rules. This API has the drawback of maybe exposing too much information (the rate of input events to other apps), but may spawn some ideas.
