Do you have any idea what the current direction is(if any?) that they are moving in? I'm mostly familiar with the use of tokens; Golang using Context and C# using CancelationToken. I currently utilize cancellation tokens myself in nodejs(TypeScript) when creating libraries or wrapping the stdlib event/stream based stuff.
