TL;DR: Some browsers already started doing exactly that. Early results so far seem rather encouraging. > We improved the performance on a vast swath of the mobile web while causing problems for a very small number of developers/sites and virtually no users (we've heard almost no complaints from users about broken sites). Our data suggests we made the right trade-off for the web platform as a whole and for Chrome as a product.
