Yeah that's what I meant. To me re-using the IDL would be a big plus because then all data can always be converted from one format to the other.

The reasons you gave make sense, although I'm not super familiar with the RPC aspect of protocol buffers so that's new to me.

For cases that don't use features specific to one format or the other, it should be easy to write a tool that automatically converts between schema formats, FWIW.
