But this isn't a js churn problem. Even if updates only happen every 6 weeks, that means that unless the majority of devs update their links every 6 weeks the distribution of links out there will be spread out enough to be nearly worthless. And while updates every 6 weeks might seem crazy to you, unless we just don't version the links (which seems like a terrible idea), even simple bugfxes blow the whole system. Plus CDN hosted systems come with a bunch of other downsides. Lack of http2 pushing, tree shaking and bundling doesn't work, being able to compile with your own settings, and more. CDNs aren't the solution here, something like using service worker and/or an "install" process for web apps will solve all of these and more.
