Following https://github.com/w3c/mediacapture-image/pull/248#discussion_r473096602,

Web developers can already monitor the camera with PTZ permission with the permissions API to detect changes.

```js
const panTiltZoomPermissionStatus = await navigator.permissions.query({
  name: "camera",
  panTiltZoom: true,
});

if (panTiltZoomPermissionStatus.state == "granted") {
  // User has granted access to this website to control camera PTZ.
}

panTiltZoomPermissionStatus.onchange = () => {
  // User has changed PTZ permission status.
}
```
