I would like to discuss with this group a proposal to solve the following use case:
For example, for services like Search, it means that the very first response from a server will contain non-localized results, and a second roundtrip would be required to refresh those results (assuming Geolocation permission is already granted for the origin).
It looks like Client Hints (CH) would be a great mechanism to solve this use case, so I started a draft trying to explain how a CH-extension could look like. You can find it here: https://github.com/luisbargu/geolocation-client-hint
It would be great to get your opinion on this, and whether this is something that might be interesting for people in this group.
