I thought that could be encoded by a FlightData with only app_metadata
set. I think I understand your position now: FlightData should always
carry (some) data (with optional metadata)?
That makes sense to me, and is consistent

It might be because the outdated Xcode version we use, perhaps brew has

Hey David,
RE: Async: I was trying to match the pattern we use for doget/doput for
async. Yes, more thinking java given java grpc's async always pattern.
On the comment around the FlightData, I think it is overloading the message
