Describe the Bug

The app renders twice when using rewrites in next.config.js. This is the demo:
https://stackblitz.com/edit/github-xxgqsj?file=next.config.js

Expected Behavior

It should render once only

To Reproduce

const moduleExports = {
  async rewrites() {
    return [
      {
        source: '/index2',
        destination: '/index3'
      }
    ];
  }
};

module.exports = moduleExports;

Hi, this is currently expected since the page being rewritten to is an automatically statically optimized page which means we need to ensure we parse the rewrites on the client and collect any params after hydration so that they can be provided in router.query.

I'm going to close this since it doesn't appear to be a bug
