Interesting but it is another technology increasing the complexity of building web sites, also to consider what happens with chains of dependencies and scripts loaded by things like require.js. I don't think it's required, browsers should just have an arbitrary limit of resources a single tab can use, useless the user promotes it somehow (like unity webapps) or apps running in an electron wrapper. I'm all for Google and Bing analyzing client side performance and penalizing in ranking those that are considered abusive but pushing the responsibility to all eyeballs doesn't seem like a good idea to me. This is Ilya Grigorik though so somewhat desired to retract my opinion.. wait.. click add comment
