The new feature will introduce new Document Policy configurations that will help developers apply performance constraints to embedded content.
These configurations will include limits on oversized assets, JavaScript resources, and system resource usage, among others.
The proposal is divided into four categories: basic, early-script, globals, and script.
The basic category encompasses fundamental web development best practices to ensure websites are optimized for performance across various environments.
The globals category entails imposing limits on overall media and system resource usage during interactions.
The script category enforces restrictions on complex JavaScript code to further enhance performance.
The host app serves its main document with Document Policy directives to enforce on the embedded content.
Developers can apply these policies individually or combine them to achieve the desired level of performance constraint.
