Agreed on that. YYYY-DD-MM isn't used in the real world AFAIK, and it's
reasonable to treat it as an error.

Other than me, I think you mean. dd/mm/yyyy and mm/dd/yyyy are
inherently ambiguous in the real world, and when you can clearly
determine what the intended meaning is, I think it's more reasonable
to assume the datestyle isn't set correctly than to reject the data.
