In Rust debugging and stacktraces are perfectly fine because async/futures compile to a perfect state machine.
They are not perfectly fine. If a task panics then you will get the right stack trace, but there is no way to get a stack trace for a task that’s currently waiting. (At least not without intrusive hacks.)
Would this be considered an intrusive hack?

I assume that answers your question.
So once it's out of the experimental stage it won't be an intrusive hack anymore?
