The best way to do this is by introducing a new Client Hints DevTool issue <https://docs.google.com/document/d/1lDEvj8tMeuvUs1HTTqL-44YiI-7ljeQkusM_WhUfIeE/edit> . Blink component Privacy>Fingerprinting <https://bugs.chromium.org/p/chromium/issues/list?q=component%3APrivacy%3EFingerprinting> Motivation Client Hints <https://www.chromestatus.com/feature/5995832180473856>, a method to request information about the user's device or conditions, have been implemented in Chrome, but since the initial implementation the naming scheme has changed. If implemented, this proposal would alert developers using `dpr`, `width`, `viewport-width`, and `device-memory` to migrate to use `sec-ch-dpr`, `sec-ch-width`, `sec-ch-viewport-width`, and `sec-ch-device-memory` respectively. The three network related client hints with legacy names, `rtt`, `downlink`, and `ect`, will not be updated as they may be replaced by different hints in an independent process. TAG review Not needed Risks Only Blink implements client hints and we are not (yet) removing any current ones, just pushing developers to use the corrected names. If usage permits, we will remove the legacy names down the line in another intent. Interoperability and Compatibility Gecko: No official position; mild positive signals. <https://lists.webkit.org/pipermail/webkit-dev/2020-May/031198.html> Firefox: UA Client hints considered non-harmful <https://mozilla.github.io/standards-positions/#ua-client-hints> Web developers: Positive interest from Cloudinary <https://discourse.wicg.io/t/responsive-image-client-hints-call-for-review/5470> Is this feature fully tested by web-platform-tests? N/A (the issues tab isn’t in other browsers) <https://chromium.googlesource.com/chromium/src/+/refs/heads/main/third_party/blink/web_tests/external/wpt/client-hints/> Tracking bug https://crbug.com/1227043 Link to entry on the Chrome Platform Status https://www.chromestatus.com/feature/6658223894429696 -- You received this message because you are subscribed to the Google Groups "blink-dev" group.
