It is surprisingly difficult to make synchronisation work between two devices that might run different hard- and firmware and even potentially software versions. Cloud based APIs as middleware is soo much easier in comparison.
I am completely with you conceptually, but from experience I can tell you that even if there is a commercial incentive to allow for local communication it takes a few days to get it working with the cloud and months to do it locally only. And you really need to know what you are doing to make it safe and reliable in all eventualities.
