Not only is it not productive, it's disingenuous. After all, tihs is a bug that in the worst of cases you're going to be hit by only once (unless you're a masochist), so whoever you tell 'don't do that then' that has just experienced your bug already knows that.
It's the people that haven't experienced it yet that are at risk, and you can't tell those 'don't do that then' preemptively.
