Possibility to flatten nested routes

[SimonChaumet]

Feature Request

It would be really nice to have a way to flatten the routes of the components.

Example

In my application I have public routes and private routes, so I created a component Public which has a router, and my public routes inside, and I have an equivalent for private routes. I want each of them to be at /*, but doing so make the library only choose the first one.
The Public and Private components are just for organization.

E.g :

const Public: React.FC<RouteComponentProps> = () => {
  return (
    <Router>
      <Redirect from={"/"} to={"/login"} noThrow />
      <Login path={"/login"} />
    </Router>
  );
};

const Private: React.FC<RouteComponentProps> = () => {
  return (
    <Router>
      <Profile path={"/profile"} />
    </Router>
  );
};

const App: React.FC = () => {
  return (
    <Router>
      <Private path={"/*"} />
      <Public path={"/*"} />
    </Router>
  );
};

Implmentation

I am new to this library (coming from react-router for an updated version of my techno) and the code doesn't seem very explicit to me, but as I saw the corresponding code is utils.pick but I don't see how to modify it correctly.

I just saw it, but it could also be great to allow absolute paths in nested routes
