I think there's one critical thing that wouldn't be handled by this approach, and it was the primary reason I suggested a new event and not piggybacking on an existing one: I find the need to *cancel* (by calling `preventDefault()`) the auto-focus behavior at least as compelling as the ability to listen for or articifially fire it. There have been times this automatic behavior has been quite annoying because of accidential ID/hash overlap. There's also times when it would be nice to, UX-wise, let the user decide if they want to scroll or not.
