I've always taken the opposite route, and insisted that my debug text be as profane as possible, to ensure that I wouldn't possibly ship it with them included. 99.9% of the time, this seems idiotic, and it is, but while it does force me to be careful (which doesn't remotely outweigh the self-imposed idiocy), there was this one time where it did benefit me quite impressively. when a co-worker was trying to take credit for having written a web app that he literally wrote zero code for. He would get there early in the morning before I could and schedule product demos to management so he would get all the credit for what was essentially my pet project. That all worked great for him until one of the error states insisted that the managers of the Fortune 50 company I was building this for all do something profane.
