Extend Dynamic Routes

[kratess]

Goals

A page like website.com/@user cannot be create with today next router. It must be done using auxiliary pages with rewrites

Something like this:
Creata a page /entity/page.tsx

  async rewrites() {
    return [
      {
        source: "/@:username",
        destination: "/entity/:username"
      }
    ];
  },

Non-Goals

No response

Background

This solution has a problem. The page is still available by just going to /entity/user and not only by goin /@user

Proposal

Add to the dynamic router possibilities of such routes.

Routes like:
/@[username]
/shop-[shopname]
