By library instrumentation we mean a standalone instrumentation that can be used without the agent. wrapper integration isn't part of our terminology. I can understand that you mean that the library offers two kind of instrumentations, one that is based on interceptors and the other one that wraps producers and consumers, but for casual reader imo this sentence does not make sense.

@laurit The word “wrapper” felt out of place since it wasn’t used anywhere in any metadata.yaml, so I agree it should be removed.

The Kafka 2.6 wrapper library currently supports the header capture feature, but the interceptors are not supported yet.
Additionally, I clarified the Kafka 2.6 metadata, adding that the Kafka 2.6 library can be accessed via either the wrapper or interceptors, and added the missing configuration options.
