Again, this may be a poor operational choice for those outside of Google, but they have also been quite clear that Go is built for the problems that Google has. If your problems are different, it may not be the right tool for the job. A hammer doesn't have to be able to cut wood. There is no harm in choosing a saw instead.
>the Go authors have always strongly promoted that you fork and maintain your dependencies
And you said that in response to a need for stack traces and specific error types.
Burdening yourself with maintaining a fork of a third party library for that specific purpose is what I'm calling insane, and I don't think the Go authors have ever suggested such a thing.
Which is true. Their stance on maintaining your own forks is pervasive through all the tooling and their explanations of how the tools are designed to be used. There has been emphasis that if you want the tools to work well, you need to fork and maintain your dependencies.
You are, of course, free to do whatever you want. You can even feely let a random third-party maintain your dependencies, and hope they don't break anything, if you so wish. Many do exactly that. Despite what some people like to claim, the Go authors are not benevolent dictators that completely rule how you must develop software. They've simply published tools that worked for them, and granted a license that allows you to use and modify them in any way you see fit.

Technically the discussion was about how stack traces aid in debugging. It is a fair point. They most certainly do. And if you are interested in the stack within a third-party library, that suggests that you intend to debug said library.
If you are debugging a third-party package, you have already decided to fork it by virtue of what debugging requires. Adding stack traces to ease debugging of the package, if you so desire, is not a great undertaking on what is already a fork you have decided to maintain. You, of course, can submit your changes to the upstream maintainer, but in the meantime you are still holding on to a fork that you have decided to maintain. There is no guarantee that anyone else will want your changes. There is really no escaping that fact. It is not insane. It is simply pragmatic.
If you are only ever going to maintain your own code, the stack trace up to your call out to the buggy third-party package will still be available, if you choose to provide it, allowing you to work around or otherwise deal with the buggy package in your code.
