title: Is there an option to disable a plugin in babel when using a preset?
body: <p>I am using <a href="http://babeljs.io" rel="noreferrer">babel</a> with <a href="https://babeljs.io/docs/plugins/preset-es2015/" rel="noreferrer">babel-preset-es2015</a>.</p>
  
  <p>Is there a way to disable a specific plugin from within the 'package.json' configuration to avoid having to fork this preset just to remove one plugin?</p>
