I think a better model would be for the site itself to provide the modules, but the browser will hash and cache them for the next site that may want to use the same module.

This way, there's no central authority that determines what is common enough.

This model does not allow for versioning. For this model, it would be risky to allow it (one website could provide a malicious model that infects the next site you visit).
