No, HTTP caching and PWA web worker caching works fine. (In fact, web workers require HTTPS to even function.) Eric Meyer's "HTTPS busts caching" complaint refers not to HTTP or web worker caching, but man-in-the-middle local servers caching responses. It sits between the internet and your local box, and serves cached requests. This breaks with HTTPS, which is designed to break man-in-the-middle attacks.
