It doesn't address navigations not triggered by user actions (e.g. <meta refresh>, location sets off timers, etc). Rigorously defining things like "the user action that triggered the navigation" in a future-proof way might be tough too... Maybe it's worth putting in the work to get this more complex model defined, of course. It really comes back to what the navigation timing bits are trying to measure. Are they measuring the time somewhat under the control of the target server, or things completely outside its control (like beforeunload dialogs on previous pages or the time it takes a browser to spin up a new rendering context)? -Boris
