This is fine, but it's too bad it did not mention the cardinal rule of goroutines on prod, which is "before starting a goroutine make damn sure you know how it will stop".

Goroutine leaks in prod are no laughing matter. They are difficult to debug without killing the process, and that's only useful if you are sure you're going to get stderr to get the full traces of all goroutines.
