You can tell the system which Wifi networks are metered, at least since Lollipop if not earlier.

How? Long pressing brings up nothing relevant (and don't get me started on hidden functionality like that), no swipe actions in the wifi settings, if it's there it's not obvious.

On 8.1, it's in Network & Internet/Data usage/Network restrictions. It does seem odd that they put it in the data section, not the wifi section.
