Has there been discussions about handling private data in Private content? Yes - and there have been efforts in making that possible in OStatus, but since OStatus itself is just made up of other specifications it currently awaits those other specifications to get extended in a way that supports this - not sure what the current status really is.
I personally though would prefer to have the main use case - the one with just public data - work first and learn from that and get that rolling before moving to the more complex stuff.
