maybe not so much safe as reliable?

-[`react-broadcast`](https://www.npmjs.com/package/react-broadcast) provides a safe way for React components to propagate state changes to their descendants deep in the component hierarchy, bypassing intermediaries who `return false` from [`shouldComponentUpdate`](https://facebook.github.io/react/docs/component-specs.html#updating-shouldcomponentupdate).
+[`react-broadcast`](https://www.npmjs.com/package/react-broadcast) provides a reliable way for React components to propagate state changes to their descendants deep in the component hierarchy, bypassing intermediaries who `return false` from [`shouldComponentUpdate`](https://facebook.github.io/react/docs/component-specs.html#updating-shouldcomponentupdate).
 
 It was originally built to solve issues that arose from using [`react-router`](https://www.npmjs.com/package/react-router) together with [`react-redux`](https://www.npmjs.com/package/react-redux). The router needed a safe way to communicate state changes to `<Link>`s deep in the component hierarchy, but `react-redux` relies on `shouldComponentUpdate` for performance. `react-broadcast` allows the router to work seamlessly with Redux and any other component that uses `shouldComponentUpdate`.
