I feel like error handling in Node hit a nadir in 10.0 due to async function stack traces being so truncated. I started in the industry when Java was young and while I appreciated stack traces plenty, I hardly ever had to deal again without them, and you really do come to depend quite a lot on this behavior.

Officially we are upgrading to 12 for perf, but I was the first (and will probably be the primary) contributor to that work because I want everyone to have decent stack traces again. Our code has too many layers of abstraction, and working without full traces is adding insult to injury.
