   @suremarc  can you remind me why we would need to pass a `FlightInfo`? I 
think we could send the required information as part of the payload of the 
stream, right?
   
   For example
   
   DoExchange
   
https://github.com/apache/arrow/blob/aded7bf37686a16fc4b0649ab97231427a219d7b/format/Flight.proto#L127
   
   Sends a stream of `FlightData`
   
https://github.com/apache/arrow/blob/aded7bf37686a16fc4b0649ab97231427a219d7b/format/Flight.proto#L495-L520
   
   And the  `FlightData:: flight_descriptor` field has the embedded cmd message 
(in which FlightSQL messages are embedded)
   
https://github.com/apache/arrow/blob/aded7bf37686a16fc4b0649ab97231427a219d7b/format/Flight.proto#L310
   
   
   
   FYI @kallisti-dev who is also working on stateless prepared statement 
execution
