I actually like having software and hardware that can be idle. I find it quite peculiar that some app/window/page I'm explicitly not interacting with should be doing work because I'm not interacting with it.

The idea is that you schedule low priority work to happen with requestIdleCallback (which this is just a wrapper around), so it doesn't impact as much higher-priority tasks like responding to input or animations. For example, you may schedule periodic API polling (and JSON response parsing) using this API to prioritise user input handling. I would guess (but not know!) that the browser could de-prioritise these tasks even further when the browser decides to (such as when in the background).
