Google Chrome Developers says:

The new WOFF 2.0 Web Font compression format offers a 30% average gain over WOFF 1.0 (up to 50%+ in some cases). WOFF 2.0 is available since Chrome 36 and Opera 23.

Some examples of file size differences: WOFF vs. WOFF2

const getNewExecutionContext = markup =>
  new Promise(resolve => {
    const iframe = document.createElement('iframe');
    iframe.style.display = 'none';
 iframe.setAttribute('src', 'about:blank');

// === Identifier rewriting for the ES6 module transpiler ===

// Proposal for minifier-friendly ES6 module transpiler output.
// This is for cases where we don't require any existing module
// format (AMD, CommonJS) and just want to emit a blackbox IIFE
// that uses modules internally. Those cases are Ember's normal
// global distribution (ember.min.js), as well as ES5 generated
// by the upcoming ember-cli ES6 stack.

// Do you all think this could work?
