Seems crazy because when I watch those athletes mixing those little jerky interludes into their tumbling routine, elegance is the last thing that comes to mind. World-class gymnasts must be the worst dancers around.
That's kind of unfair, in a way. They aren't that bad. It's just that you are used to seeing people who are very good. Try making a video of yourself dancing. It doesn't look like you think. (This is a painful fact learned by any hobbyist dancer, like me.)
But it's true we don't necessarily want to see someone who is not really good. And by not good meaning that they don't spend a lot of time refining that aspect of the routine.
It is up to the sport itself to decide what they want to emphasize and how they want to judge competitions. And it is up to us as viewers to voice our opinions.
I think I am with you in my opinion of some of the dancing. I would rather see a gymnast reflect the music less rather than do some unattractive dancing.
And when it comes to differences between men's and women's floor routines, that doesn't bother me one bit.
