tl;dr: Enable async-await syntax without including the whole babel polyfill.
Under the hood, this addon configures babel's async-to-generator plugin to use RSVP.Promise.
The babel plugin defaults to use native Promise which breaks in old browsers.
The transpiled async/await code needs regenerator-runtime.
This addon will check target browsers, babel options to properly import the asset (~2.5kb after gzip).
The browsers list support generator and async-await from babel can be found at babel-preset-env/data/plugins.json.
Yes, adding ember-async-to-generator to your addon's devDependencies will not affect host apps.
Notice your addon's local development will also have async/await available. To avoid async/await code from addon, you can add lint rules to make sure async/await is test only.
ember-maybe-import-regenerator and ember-maybe-import-regenerator-for-testing only imports the regenerator assets, but your app will still be using native Promise.
ember-async-to-generator will check existence of those two addons to avoid duplicate import.
If you wish to only import the asset in test, you can install ember-maybe-import-regenerator-for-testing and eslint-plugin-disable-features, see this blog post.
