Question: does OnEmit need to know the value of include_trace_context?

Related question: should a log's trace context fields be populated if include_trace_context=false and context is explicitly passed? I think yes. However, for languages that rely on explicit context because no implicit context is available, there's no point to having the include_trace_context parameter since it doesn't change any behavior.
We might actually consider removing include_trace_context, since setting it to true seems to only be syntactic sugar for explicitly setting an empty context.

I agree, we should consider it, it is a source of confusion. Created a separate issue here: #3394

The
contextparameter passed in to LogRecordProcessor.OnEmit() should not be affected by theinclude_trace_contextconfiguration, since the Context may contain other information than just the trace context.
