Even if the bundle is always cached locally, a large bundle can hurt startup performance. A little discipline goes a long way. You probably don’t need to fight against every few kb, but having a bot post the bundle size in every commit can help a lot. If you think you can ignore it, you will, until you can’t ignore it, and then it’s a very annoying problem to solve.
