Thanks for the reply, Ryosuke! Just to clarify, the `metered` attribute would be a manual user setting, not a browser heuristic. This means you could easily mark your all-data included WiFi at home as metered if you wanted to, or, on the opposite end, mark your roaming data plan you purchased for a ton of money at the airport as unmetered. None of this happens without the user voluntarily revealing the information.
Why would it be implemented as a manual setting in the browser, rather than a per-connection setting controlled by the OS? On Linux, NetworkManager already knows whether each network interface is metered or not. Users can override the choice in the unlikely event it guesses wrong. Why should a web browser offer a second level of override in addition to existing system settings? Are you planning to offer a browser-level override for every network interface separately, or just one single toggle that doesn't consider which network interface is in use? Michael
