Does DJI plan to add Active Track added to Robin S in the future?

Hello and good day Zap. Thank you for reaching out and for the inquiry. I will forward this thread/feedback to our DJI Developers. After the evaluation of the engineers, significant suggestions or requests will be implemented via the firmware update, app update, etc. For any updates, please stay tuned to the latest news in our DJI official website at www.dji.com or by checking the Release Notes specific for your product. Thank you for your valued support.

AFAIK Active Track is based on object detection through analysis of the image which in turn results in movement control commands.
Since the gimbal has no knowledge of the image what you're shooting, there's no way to do that, hence I would think this question is somewhat unrealistic for the RoninS.
If you require this functionality, you need something like a OsmoPocket or Mavic, where the camera works together with the gimbal...
