All too often, this notion of a "default coordinate system" seems to restrict our thinking and make us believe that there are limitations on how we can orient the world. I just want to point out that the idea of a default coordinate system is really a myth.
There are still cases where it's useful to know what the coordinate system is with an identity matrix set, though. I'd be for describing it explicitly as "the coordinate system with the ModelView matrix set to identity", but avoiding the term "default coordinate system" for the reasons you mentioned.
It's interesting to note that the OpenGL spec makes no mention of a default coordinate system at all (at least none that I could find). It even states that there is no requirement for right- or left-handedness (though it does describe the conditions and settings that result in a right-handed coordinate system).
