Address why I wasn't using the rootElement feature of Ember. Just using the rootElement config option would probably work for this particular use case.
An advantage of the “ember-islands Approach” (tm) is that I can render many components on the page in different areas without needing many Ember Apps. Also all of these components can talk to each other through services since they have the same application container.
Also, testing
Also, ember-cli's ecosystem
