Re: [w3ctag/design-reviews] User Preference Media Features Client Hints Headers (#632)

> One concern I want to explore further is about the fingerprinting capabilities that the feature enables. A combination of such media feature hints can be used to allow much easier evasion for phishing or other ill-intended sites. Have you considered such scenarios?

Just wanted to note that no additional information is exposed. The same information is exposed by the [user preference media features](https://drafts.csswg.org/mediaqueries-5/#mf-user-preferences) from CSS, paired with JS:

```js
if (matchMedia('(prefers-color-scheme: dark)').matches) {
  // Send info to server that the user prefers dark mode.
}
```
