// While I claim this is a drop-in replacement, it is a little bit slower.
// If you have hundreds of links, you might spend a few more milliseconds rendering the page on transitions.

// KNOWN ISSUES WITH THIS APPROACH:

// * This doesn't work great if you animate route changes with <TransitionGroup>
//   because the links are going to get updated immediately during the animation.
// * This might still not update the <Link> correctly for async routes,
//   as explained in https://github.com/reactjs/react-router/issues/470#issuecomment-217010985.
