RFID isn't as much of an issue, as the tags are generally passive, and not always on and looking for a signal. As far as more mature: 'more efficient' is really a better wording. There seems to be a culture of excess at the moment, where the amount and frequency of data our devices send is not much of a design consideration. This is part of what MQTT addresses - more devices but smaller data payload sizes. Where we can be more efficient without sacrificing too much conveinience we should be. Ex: Just because my TV's DVR can work over WiFi doesn't mean it should by default. That sort of thing.
