		The [risks of enabling loose classes are outlined in the Babel docs](https://babeljs.io/docs/en/babel-plugin-transform-classes#loose).

		## Specifying a babel runtime version

		By default @babel/plugin-transform-runtime will [assume the oldest version of the runtime](https://github.com/babel/babel/blob/e6264a09921c60b8f18870d0a75678e4fa04f0f8/packages/babel-plugin-transform-runtime/src/index.js#L42) to avoid importing helpers that don't exist which would fail at runtime. This can result in newer helpers being inlined into modules (ex. objectSpread2) which increases bundle size.

		To avoid this you can configure the preset to use the same version of the runtime that's installed in your package.json.

		ex. If package.json has `"@babel/runtime": "^7.5.5"` then you can use:

		```json
		{
		"presets": [["airbnb", {
		"runtimeVersion": "7.5.5",
		}]]
		}
		```

		Note that this will result in a runtime breakage if the version passed into the airbnb preset is newer than the version of the babel runtime actually being used at build time.
