Got it! That makes a lot of sense. The [voting plugin](https://meta.discourse.org/t/discourse-feature-voting/40121) is already dependent on v1.5.0.beta11. Most aren’t likely to use it until v1.5 is stable. If I leave it without the export that would make it dependent on v1.5.0.beta14?

Is there much difference performance-wise and functionally in one over the other? I’m still getting my head around Ember.
