nit: Let's wrap this with log.isDebugEnabled to prevent optional and safeArg allocations when debug logging is disabled.
note: no reason to use an Optional for the safe-arg, as far as the logging system is concerned empty optional and null are indistinguishable.

While we're here, thoughts on mirroring the debug line after a traceId is set? That way we get a full sense of the scope transitions.

We're seeing instances of trace information disappearing from logs on a thread that previously had traceIds. Trying to track down where/how they're getting cleared.
