I've seen a couple of versions where they remove the skin completely and re-wrap it and they all look mad. Must stop the fat acting like a heatsink or something.
Keep in mind the general purpose of Porchetta in Italy is to then be sliced thin and eaten in a sandwich as if it was a cured cold cut rather than a Christmassy roast. Maybe keeping it leaner is also towards that. On top of that the fat content can vary a lot depending on animal age and nutrition.
