To me, it's a bad thing because the animal isn't able to ambulate normally. I really think if snakes had legs, wobbling and corkscrewing would not be seen as cute at all. I don't think it's cute. I think it's sad when an animal wants to move forward and can't.
For the same reason I wouldn't breed brachycephalic dogs (bulldogs for example), I won't breed spiders that wobble. Spiders are definitely a beautiful morph, but for me the cost of that beauty is too high.
