Ember Data with a root key. A non-standard REST protocol?

I have to make a change to my application where my team wants to remove the root keys from the JSON data. However, I really like the out-of-the box feel for this, but my team is arguing that this is a non-standard REST protocol, so we need to stay away from it.

Rather than changing my serializer to fit this, is there an argument I can put against this so that I can continue working with this out of the box? Or are they correct in that Ember shouldn't be requiring this?
