String.prototype.split is a ubiquitous part of the ES3 spec. Tracking back (#1516), I can't see a specific reason to include it in the required polyfills.

@syranide: did I miss anything?

Also all other methods there are in ES5 and IE9 supports them all and React docs says

React supports most popular browsers, including Internet Explorer 9 and above.

It's a DEV-only thing so I'm not sure if it really matters and yeah it's so old it would surprise me if you can even find a browser that lacks it today. So yeah it seems quite useless there, but then again, it's not hurting anyone either, so take my thumbs up and a shrug ;)

Might as well take this then, at the very least to avoid confusing any future contributors 👍

One thing I just noticed is that https://fb.me/react-warning-polyfills links to:

https://facebook.github.io/react/docs/working-with-the-browser.html#polyfills-needed-to-support-older-browsers

And the polyfill section it links to doesn't exist anymore. I think it should be updated to point to https://facebook.github.io/react/docs/working-with-the-browser.html#browser-support. @zpao can we get that link updated? Though honestly there isn't really a whole lot of useful details in that section, so maybe it's not worth linking to a docs page for this anymore?
