- Removes the default implementation. - Makes tracing_core::span::Current::unknown public so that implementers of Collect can use it if they didn't implement current_span() before. - Copy the old default implementation to all implementers of Collect. Co-authored-by: Eliza Weisman <eliza@buoyant.io>
