That's great. It's an entirely manual setting on Android and Windows, but I
imagine certain rules like "SSID is 'Android AP'" already would go a long
way. The way this signal is obtained is not part of the proposal, the
proposal barely focuses on reflecting what the OS provides. This does not
mean browsers couldn't add an override, but it definitely does mean that
the browser is in no way involved with guessing if the current network is
metered or not.

The current thinking is that there would be no additional permission
needed. Note that the proposal reduces the overall entropy compared to the
current API, which exposes more information:
