Maybe with the introduction of ember-cli-addons
One of the key features what ember-cli-addons (ECA) does is:
Providing a custom application tree to be merged with the consuming application. This allows you to distribute anything that might need to be imported in the consuming application; including components, templates, routes, mixins, helpers, etc.
So it's necesary to re-write the ic-*whatever-component to an ember-cli app and then import as addon. This would solve he import problem once for all developers, compared to an approach where everybody had to rewrite the ic-* to fit his app.
And did u check this mechanism used in ember-cli -> ember-load-initializers
