I agree it's not a great example, it's simply the most obvious/visible one. This would definitely be better served with position: device-fixed but encouraging this use-case in general is somewhat questionable. It has accessibility and usability concerns.
The main motivation for us in visualViewport was that we wanted to make window APIs like scrollX|Y and innerWidth|Height relative to the layout viewport. We had a long tail of bugs when pinch-zooming as a result of having these be relative to the visual viewport. When we first made this change, some authors complained about losing the ability to tell the viewport was zoomed (https://crbug.com/571297). The most compelling cases where things like "Remote Viewer App" (seeing when the remote user is zoomed in), and analytics ("how often do users zoom on my site"). These are fairly niche but on the principle of a rational platform we agreed that these things should be possible.
