Earlier quoted context omitted.
Stack traces for async code are always borderline useless in Javascript. Instead of telling me who called the offending code it just informs me that the code is executed by an scheduler in the event loop.
You create the error before doing the async operation, then throw/callback that error with additional info from the async error.
That sounds tedious in a web server where like half the functions are async. Also why is that my responsibility? A stack trace is supposed to show the call chain, not language implementation details. At a minimum `async x()` should just be equivalent to `try { async x() } catch(err) { throw new Error(err) }` (with the logger printing all nested exceptions)
