Remove babel-polyfill?

[novemberborn]

I just noticed that this package pulls in babel-polyfill. Since that shims the environment that seems like a bit of an unindented side-effect of using this package.

Instead perhaps this package should be tested with explicit Node.js versions and then the polyfill can be removed.

Oh yeah I'll ditch the polyfill. That said it shouldn't do anything where the methods already exist.
