There were some features that were dependent on firmware that wasn't ready, and I think they made the decision to get the hardware out the door with the base feature set. Some features listed in the marketing material had an asterisk next to them, with a note that they would be available with a future firmware update. Bluetooth support wasn't really working until recently, and the "sidecar" and electronic switch hook switch are two others. The nice thing about the architecture is that there is a lot they can implement in firmware, without the hardware becoming obsolete.
