Fair. I worked with Ben to integrate opentracing into docker before Kube won, and at that point it was tracing only. Tracing as in spans, annotations, and baggage spanning services. So, it has changed from call graphs/timing etc to telemetry in the broad sense.

We're talking about churn here, not my knowledge, and I think considering how you say I don't understand it we can both agree it has churned into something else. As OP said, there is a lot of churn. Too much for your common system to keep up with in the (pun intended) span of a couple years. 3 rebrands in fewer years isn't promising.
