It will look better for the project lead if there's an issue though. You can say that you enabled everything recommended by Google or w/e, following best practices, and still got pwned instead of arguing that your own security model had a tiny little flaw that no one recognized. And it frees up project hours which can either be the difference between doing the project or not doing it and/or allow you to have other project work billed to this project.
