This project was doomed from the start. The merging of OpenTracing and OpenCensus has far too much corporate interest tied up in it, which leads to these kinds of monstrosities:
The fact that they didn’t take a hard stance and define a wire format data model is going to leave this project in the same position as it’s predecessors. (OpenCensus had it right, but they threw that out when agreeing to merge with OpenTelemetry).
