(That's not a feature unique to `exact` values, but assuming you mean _specific_ values) Probably not, which I believe is why we added the convenient `true` alias for `{}` and use that in all [examples](https://w3c.github.io/mediacapture-image/#example1).
But I see no reason to outlaw it either, since the following accomplishes the same:
```js
const [track] = (await navigator.mediaDevices.getUserMedia({video: {pan: true}})).getVideoTracks();
await track.applyConstraints({video: {pan: 100}});
```
In any case, the user was arguably warned when they allowed the site to "Use and move the camera".
