Javadoc

Returns the underlying trace context for use in Brave apis, or null if this object does not represent a span.

When a span context is returned from BraveSpan#context(), there's no ambiguity. It represents the current span. However, a span context can be in an intermediate state when extracted from headers. In other words, unwrap might not have a TraceContext to return.

Why? BraveTracer#extract(Format,Object) can return partial info. For example, in Amazon Web Services, you may be suggested just a trace ID. In other cases, you might just inherit baggage or a sampling hint.
