I'm neutral about it, just like with the cage. Some swing and cage clips I like, some I don't. As long as the majority of the show clips aren't "swinging" or "caging", I'm fine with them. At only $1 a model card (the way I buy them), with over a dozen clips and the current length of the total shows, I can live with a few clips in every card that may not interest me.
Besides, there's probably somebody who would suggest, "Hey! I've got an idea! Put the model in the cage on a swing! That would be cool!"
