This will only shift efforts to extract uniquely identifiable information through side channels instead of directly. So you also need to disable javascript or redesign it to prevent side channel attacks (it's possible, but would be a completely new javascript compiler with not entirely compatible language, also this would mitigate spectre attacks).
