WiFi icon indicates connections is limited/has no internet connection

When you connect to a WiFi network and that WiFi network has no internet connection, the WiFi icon shows no indication of this it requires a few clicks to see that the WiFi connection has no internet access. Contrast this with Windows where if the connection is limited/has no internet connection an orange triangle is shown where you can see at a glance that there is something wrong with the network.

An indicator of this kind would be quite helpful, whether on the WiFi icon itself or somewhere else where it is more visible and preferably doesn't require any clicks.
