dontcallmedom has just created a new issue for https://github.com/w3c/mediacapture-main: == deviceId and Clear-Site-Data == The spec requires that > User Agents MUST rotate per-origin device identifiers when other persistent storage are cleared One of the mechanisms that exist to clear persistent storage is the [`Clear-Site-Data` header](https://w3c.github.io/webappsec-clear-site-data/). As far as I can tell, neither Chrome nor Firefox rotate `deviceId` when they encounter that header - I have a [test that shows it for the `cookies` value of the header](https://github.com/web-platform-tests/wpt/pull/31937/commits/ab9a7becfb4fe8197805f1f49499b9b37c320715), but I've verified that it remains true for `*`. (Safari doesn't implement that header). I think it would be useful to confirm or infirm whether `Clear-Site-Data` is expected to impact `deviceId` rotation (I would argue the current wording implies that it is expected), and if so, to specify under what bucket of the header (I could imagine either `cookies` or `storage`).
