I'm not sure about the best wording for "Y-scaled flat primitives". I would actually say that it should be more explicit: primitives where all Y values are 0.

Having said that, I disagree with disallowing it in the case where the scale matrix scales X, Y and Z equally. It's true that the Y portion of the scale would be ignored, but I personally feel that a uniform scale in all three axes is preferable to one where only the X and Z axes are scaled, while Y scaling is set to 1. I feel that forcing them to use a different scale matrix just because the thing they are scaling happens to be in the X-Z plane add unnecessary complexity to the part authors' jobs, and doesn't accomplish anything useful.
