+Remove Atlaskit specific process.env switches (#195)
+
+BREAKING CHANGE
+This removes the previously available process.env switches to conditionally disable the loader. 
+To restore the previous behaviour you'll have to use the `resolveLoader` webpack config, e.g. 
+
+```js
+// webpack.config.js
+const enabled = ['production', 'staging'].includes(process.env.WEBSITE_ENV) || process.env.FORCE_EXTRACT_REACT_TYPES;
+
+module.exports = {
+  /* ... */
+  resolveLoader: {
+    alias: {
+      'extract-react-types-loader': enabled ? undefined : require.resolve('./noop-extract-react-types-loader')
+    }
+  }
+};
+```
+
+```js
+// noop-extract-react-types-loader.js
+module.exports = function noopExtractReactPropTypesLoader() {
+  return `module.exports = {
+    component: {
+      kind: 'object',
+      members: [
+        {
+          kind: 'property',
+          key: { kind: 'id', name: 'Warning' },
+          value: { kind: 'any' },
+          optional: false,
+          leadingComments: [
+            {
+              type: 'commentBlock',
+              value: `extract-react-types is not being run in dev mode for speed reasons. If you need to
+  see prop types add the environment variable \`FORCE_EXTRACT_REACT_TYPES\`
+              raw: '**'
+            }
+          ],
+          default: {
+            kind: 'string',
+            value: 'Prop types are not shown in dev mode'
+          }
+        }
+      ],
+      referenceIdName: 'NoopPropTpes'
+    }
+  };`
+}
+```
