I agree it's the best option to rollup the sleeves and just fix the problem you're griping about. However, a write-up like Jason's is a valid option, too, if person doesn't have time/resources/skill for that option. Because, at that point, known issues would've been ignored by everyone up to Theo despite it being in default install and under OpenBSD's quality image. A write-up drawing attention to the issue would be justified to prevent users from placing unjustified trust in that component. Being informed lets them take action either on improving the component themselves, limiting damage it could do, or just avoiding it altogether.
Still agree that the gripe should go to the developers and Theo first.
