Timothy Chen commented on DRILL-19:
-----------------------------------

One downside is that we cannot take the DescriptorProto object produced and 
reproduce the original list schema since the embedded data is in the message 
itself not the interface. If this is not one of our goals then yes the embedded 
schema is a lot simpler.
