I disagree here:  link navigation is fundamental to the Web, and I don't
think the back and forward buttons will or should become obsolete.

I think a better solution than extra user interface is a solution like
what popup blocking uses:  pushState (like window.open these days)
should only be allowed while handling a user event like a click or a
keypress that expresses the user's choice to navigate to a different
state (like navigating to a different page).
