Yes I agree with you but you are point out the existance of low weight packages while I would say that cost is a more important constraint for drones. I guess users can argue with the idea of equipping their low-cost drone with an expensive certified ADS-B receiver. It won't be as cost effective as one may think.

Also one has to consider that the mode S transponder is using a 24bit identifier. While this has a lot of sense for modern civil aviation (there are not as many planes) the same cannot be guaranteed as soon as you have many more temporary users of your airspace (e.g. swarms of Amazon delivery drones). IMHO regulators should aim first to create an effective solution that works well for drones (e.g. allowing ATC to broadcast digital commands to guide drones if necessary, btw there is a similar effort already for commercial planes) and then find a smart way to integrate commercial and drone aviation systems.

Btw really nice product!
