Yes, it includes all of that. The benefit is that it can be integrated into the primary SoC, using less power and taking up less space...and not paying licensing fees to Qualcomm.
Power isn't a concern because the link isn't high speed. Evidence from QC shows there's no power savings from a discrete vs. integrated design.
Apple probably doesn't want an integrated design either. There's no point in wasting expensive transistors when the A-series is used in everything from $349 iPad to $129 Apple TV.
