title: Babel 6 react JSX transformer - disable strict
body: <h3>Issue</h3>
  
  <p>I'm using babel 6 for react JSX transforms. However I'm not using the react preset, I am ONLY using the 'transform-react-jsx' plugin (and trying strict-mode disable option), here is my .babelrc</p>
  
  <pre><code>{
    "plugins": [
      ["transform-react-jsx"]
    ],
    "sourceMaps": true,
    "strictMode": false
  }
  </code></pre>
  
  <p>However I have required a thirdparty javascript that uses 'with' (out of my control) which emits following error:
  [SyntaxError: foo.js: 'with' in strict mode .. ]</p>
  
  <p>So I need to disable strict mode, This is same problem as <a href="https://stackoverflow.com/questions/34778980/babel-config-strict-mode">this issue</a> however I am NOT using es6/es2015 stuff, only jsx transforms. </p>
  
  <p>With babel 6 there is no blacklist and I've only specified ONE plugin, so I'm suspect there is no way to disable.</p>
