It's the same with dogs, "breed standards" have a lot to answer for, as they nearly always are detrimental to the health of the animal.
You've only got to look at a picture/drawing/painting of a 18th/19th century Bulldog to see how different they were back then; much healthier, more athletic and, in my opinion, much better looking animals before they were bred to have stubby legs and a short snout that causes breathing issues.
