What is the “key” which changes on every route change with connected-react-router?

When an action for navigating to a route is triggered, an action triggers a new state where the router.location.pathname changes according to the browser's history.
Another property changes as well: router.location.key, to a new random string.
Even when the pathname itself doesn't change (clicking on a link to a page from the page itself), the key still updates.
What's the purpose of the key property? In which situations would I want my own state to have a randomly generated key which updates on very action dispatch? Why is it not a number which simply increments?
