Baggage API vs Activity.Baggage

[ghost]

Question

It's not clear to me what exactly the relationship is between Activity.Baggage and the new Baggage API. It seems initially OpenTelemetry Baggage was implemented using Activity.Baggage and then it was changed again. I'm adding OpenTelemetry support to my RPC library and I'm wondering why/if I need to pass around activities and baggage when activity seems to contain baggage.

Activity.Baggage does not conform to the OpenTelemetry concept of Baggage. (it existed even before OpenTelemetry).
If you are interested in using Baggage as per OpenTelemetry, then use the Baggage API from OpenTelemetry.API package.
