Does babel-preset-meteor need to be installed explicitly?

Now that babel-preset-meteor has been merged into the main Meteor repository, does it actually need to be installed explicitly? Or will the following .babelrc file Just Work™ without explicitly installing the babel-preset-meteor package?

  "presets": ["meteor"]

You will need to install it as it is an independent package on npm. It is in the Meteor repository just for management reasons, it doesn’t mean that it has been integrated into Meteor itself.

Thanks for the clarification @storyteller
