Error when adding babel-plugin-transform-flow-strip-types

See original GitHub issue

I’m trying to integrate ember with Flow Type Checker, but getting an error during ember builds:

File: ember-ajax/ajax-request.js
The Broccoli Plugin: [Babel] failed with:
TypeError: The plugin "transform-flow-strip-types" didn't export a Plugin instance

//ember-cli-build.js
module.exports = function(defaults) {
  var app = new EmberAddon(defaults, {
    babel: {
      plugins: ["transform-flow-strip-types"]
    }
  });

The error seems to originate from .../node_modules/ember-cli/node_modules/broccoli-babel-transpiler/node_modules/babel-core/lib/transformation/file/plugin-manager.js:165:13)

    // validate Transformer instance
    if (!plugin.buildPass || plugin.constructor.name !== "Plugin") {
      throw new TypeError(messages.get("pluginNotTransformer", name));
    }

transform-flow-strip-types is a babel 6 plugin. ember-cli-babel currently targets babel 5.
