There is reason to expect this if you want some expectation of eating what you're being sold. It's an extension of reasonable labelling. It's interesting you pick out cheddar. Consider Cheddar cheese - much of it was so direly awful as barely meeting requirement to be called edible let alone cheddar. Labelling your cheese "cheddar" should give me some expectation of production process (it can't be cheddar if it's not been cheddared or aged) taste and texture just as labelling Fire Engine Red paint gives me expectation of colour inside the tin. Would it be stupid protectionism to be disatisfied that I received pale pink paint in the tin? Fortunately there's an EU PDO protection for Cheddar - "West Country Farmhouse Cheddar", so this is what I now usually buy. It requires a minimum aging of nine months and that the milk come from the same farm producing the cheese. It's a dramatically better product.
