Apropos this, here is something about “quest issues” that @jar1 (not sure the ids are for the same user) just dropped on slack for marshalling contributors. At least in some cases it was very successful.
I should add that the use case was very similar: These are exactly the steps you need to take to improve this error message, even if you have never contributed to OSS. Or course for AD rules the experience needed to enter is a bit higher.
