Quick can is very good at breaking up your monolithic code base into lots and lots of small chunks. And the reason why that is important is because it's very easy to concapinate chunks together. All many components on a page are components that execute exactly once. If you have a reasonable framework, then that code still runs exactly once, but it doesn't have to run on the client. So this is where defined grain chunking comes in so that we can like break up parts pieces that are unneeded and don't even bother shipping them to the client.
