As Vodafone's comments on this API last day, I agree that it’s necessary to give users the information about the current network because they will pay for that.
Actually the reason of our suggestion about the attribute 'type' is from this concern. The attribute 'type' will not be used to determine the network capacity, but tell the users what kind of data connection is using only. 

For example, I'm watching internet video using WiFi, but it disconnects for some reason, and the mobile reconnects internet through 3G access point, which is usually charging according to the data flow. If we failed to tell the user this change as soon as possible, the user will have a big problem when he receives his bill at the end of the month. If we have the parameter '.type', we can give users an explicit information in application when the network is switching and reconnecting.

On China Unicom's WoPhone introduced on this F2F meeting, we will give this information in applications to users. Because we want to reduce the bill confusion from users.

Best Regards.

Actually, the type attribute was in the previous version of the specifications and have been removed on purpose. The reason is that the type attribute could be used to fingerprint users and also to do bad assumptions regarding the connection characteristics.

You should be able to find more information about this here:
