Thae's a nice ideal, but if you need to get something working, nothing beats searching for the error message.
The original package maintainers could write instructional materials that start from the errors, but I suspect that's too hard. Without specific training, it'll always be easier for third parties to provide ad hoc than first parties to produce as part of release.
