I am sure `ScopedContext` can be as fast as `ThreadContext`. I pushed a JMH benchmark we could improve to get some measurements[1]. It's a work in progress, I am not sharing the first results, because the two differ by almost two orders of magnitude. I suspect some aggressive JVM optimization is taking place.
