babel: standalone does not work in ES5

I’m trying to run @babel/standalone in an ES5 environment. I’m not sure this is target platform or not?

Anyway, one way to try this out is to use a really old version of node (0.10 for example)

Input Code

yarn add @babel/standalone
nvm install 0.10
nvm use 0.10
node node_modules/@babel/standalone/babel.js

Expected Behavior

I was hoping this would work. It works on the 6.x branch

Current Behavior

$ node node_modules/\@babel/standalone/babel.js

/src/test-babel/node_modules/@babel/standalone/babel.js:6578
var BLOCK_SCOPED_SYMBOL = Symbol.for("var used to be block scoped");
                          ^
ReferenceError: Symbol is not defined

Possible Solution

Are we not including the ES6 polyfills?
