But you can't fully detect the changes without the front-end. When an API changes, so does the official front-end that is interacting with the API. We need to track changes to the HTTP API requests coming from the front-end. You can't detect those changes just by hitting the APIs directly. If the official front-end changes how it sends data to the back-end, we need to change to match it. We also need to detect and react to UI layout changes, and the headless browser is the only real way to do that.
