A Perfect Potato?

Last week, I was watching a programme on the state of agriculture in Oz and heard that 25% of all potatoes  harvested are discarded because they are the wrong shape.  The wrong shape? Are we absolutely stark raving mad?

I was reminded of an article - https://straight cucumbers - from Atlas Obscura sent to me from the indomitable BM. For afternoon tea (never "High Tea", please) cucumber sandwiches needed straight cucumbers and this is how they did it.  

They might have been absolutely barking mad but do we need uniformly shaped potatoes?  It must break a farmer's heart.
