The quality of experience with the mobile web remains poor, partially as a result of complex websites and design choices that worsen performance, particularly for users in suboptimal networks or devices. Prior proposed solutions have seen limited adoption due in part to the demand they place on developers and content providers, and the performing infrastructure needed to support them. We argue that Document and Permissions Policies -- an ongoing effort to enforce good practices on web design -- may offer the basis for a readily-available and easily-adoptable solution. In this paper, we evaluate the potential performance cost of violating well-understood policies and how common such violations are in today's web. Our analysis show, for example, that controlling for unsized-media policy, something applicable to 70% of the top-1million websites, can indeed reduce Cumulative Layout Shift metric.
