Yeah, I've been quite happy with this feature. Usually, if Android temporarily avoids the network, you weren't going to be able to use that network anyways. If you don't want Netflix using mobile data, restricting it from using mobile data would be wise. Before this feature was in Android, I more frequently found myself attempting to use a poor network, turning off Wi-Fi to use mobile internet, and forgetting to turn it back on. For this reason, this feature has saved me more data than it has used needlessly.
