FWIW the OpenCensus website says: OpenCensus and OpenTracing have merged to form OpenTelemetry, which serves as the next major version of OpenCensus and OpenTracing. You'd never know it if you just looked at the other two websites, though...

And Jaeger has always been on top of OpenTracing. So I guess there's more unity than it seems.

Yeah, it’s all getting stitched together. I would expect v1.0 of OpenTelemetry coming in March, with W3C Trace-Context headers as the default format for context propagation.
