That's the problem: no one is using plain vanilla HTML pages with lean JS/CSS anymore. Just go to any news website, disable your cache, disable any adblockers you might have and see the total data transferred or number of network requests. Example: http://edition.cnn.com/2017/06/26/middleeast/western-wall-israel-netanyahu/index.html http://edition.cnn.com/2017/06/26/middleeast/western-wall-is... That link is in the frontpage of cnn.com right now. I disabled my cache, disabled uBlock and refreshed the page. 329 network requests and 3.9 megabytes of data transfer later, the page is still loading.
