We cannot think of a good use of a structured Body in the logging APIs. All of the logging libraries that we are aware of produce log body (message) as a string. Because of this we think that it is reasonable to limit logging APIs to accept the body as a string only and the structured data that logging libraries allow should go to the attributes.
This limitation likely needs to be added as an amendment to OTEP0150.
