After reading the specs, this sounds like an awful lot of complexity for something that should be simple and low cost. The spec also seems to be very loosely defined, more like a recommendation than a spec. This means you'll likely have to integrate a library and that library will be the authoritative source of truth as far as the expected behavior is concerned.

That's the nature of having existing players with significant market share but no standardized spec. OTel was/is in the same boat where in order to be a successful project, first you have to integrate with the products orgs are already using.
