What exactly does Ember.MODEL_FACTORY_INJECTIONS do?

Question

I am using the Ember CLI, and by default it seems to install Ember.MODEL_FACTORY_INJECTIONS = true;in app.js.

I tried commenting on this line (and set it to false) and then my application seems to behave in some kind of strict mode. I got a bunch of unsuccessful statements because some of my Model relationships did not explicitly indicate otherwise.

This is the exact error:

You defined the 'account' relationship on (subclass of DS.Model), but multiple possible inverse relationships of type (subclass of DS.Model) were found on (subclass of DS.Model). Look at http://emberjs.com/guides/models/defining-models/#toc_explicit-inverses for how to explicitly specify inverses

Using the default Ember CLI application c Ember.MODEL_FACTORY_INJECTIONS = true;, I did not receive these errors. Therefore, I am convinced that this flag somehow changes the basic behavior.

I apologize!
