Sunday Question of the week

Arabians are bred not only with specific foresight as to how the body is built but with consideration to the conformation of the head. Other horses i.e. thoroughbreds, quarter horses, etc. etc. all have varying head types, and while Arabians have slight variations in the shape of their faces, Arabian breeders tend to have the same general goal for the head when thinking about their foals. Are Arabians the only horse breed that have such guidelines for the head?
