Async/await and own .babelrc is broken

I wanted to customize my babelrc to have a few additional plugins. Based on the 1.3.2 release notes, it totally looks like I could. So I made it like this:

{
  "presets": ["babel-preset-meteor"],
  "plugins": ["add-module-exports", "transform-class-properties"]
}

However, now whenever I attempt to use async/await, it completely breaks, saying that meteor code must run within a fiber.

Exception while invoking method 'add address' Error: Meteor code must always run within a Fiber.

If I completely remove the .babelrc, it appears to work.
