Are single-lettered word models supported in EmberJS?

I cannot really pinpoint whether the issue is with Ember or Ember data, or if it's even an issue, but here's what happens:

Let's say you've got your model called tell_me_a_story. This will be the name that your JSON should provide, should you be using ActiveModelAdapter.

Regardless, when Ember or Ember Data process it internally, it'll camelize it and it becomes tellMeAStory, correctly indicating that "A" and "Story" are two separate words.

However, when internally it is decamelized to lookup for the model, the decamelize function will convert it into tell_me_astory.

This final behavior seems flawed to me, but when looking at the tests that derived this behavior, it is actually intended to manage acronyms in that fashion. (Compare the following example with the "innerHtml" that I would expect for camel casing multi-letter acronyms.)

QUnit.test("converts a camelized string into all lower case separated by underscores.", function() {
  deepEqual(decamelize('innerHTML'), 'inner_html');
  if (Ember.EXTEND_PROTOTYPES) {
    deepEqual('innerHTML'.decamelize(), 'inner_html');
  }
});

So, which is the correct way to use single-letter words in models with Ember? Are they even supported?
