I think a lot of people want what you mentioned. But I also think that even if stack support is implemented, they will "keep it simple" and pass the responsibility of extracting the location/details of your code from the stack trace to, you. That will give rise to everyone writing there own variety of utility/common stack parsing methods and then libraries will spring-up that provide such conveniences and it'll go on to become its own thing.

I feel like that is Go's underlying theme: "we don't provide last-mile-connectivity; how else will the ecosystem grow?!"
