Can the same RFID3 SDK be used with the RFD8500 and RFD2000

Is it possible to use the same SDK for both the RFD8500 and the RFD2000? It seems that RFID3 is used with the RFD2000 and the RFID3 is the latest available for the RFD8500 sled.

Briefly looking through the documentation it would seem that the functions and syntax are the same or very similar. If this is not possible are there plans to combine the two?
