Instead of an independent device with its encapsulated nugget of information, you have a parsed 'summarized' data stream subject to the control of....who? The Airline? the Airbus/Boeng? or the NTSB/CAA body?
The whole idea is a nonstarter given the resistance by pilots and their unions to the FDRs being read/analyzed in the course of routine operations.
I am not holding my breath for the recorders. I feel that those in the know already have a pretty clear picture of what happened and why and hopefully are acting on it. For the rest of us - the investigation will drag on and on until some appropriately anodyne language is found that all parties can live with.
