Why would you use yafray without raytracing?

Something that donned on me recently… Elephant’s Dream was rendered with Yafray, or so I heard, but all or most of it was rendered without raytracing. So here’s my question: Why would you render with Yafray when you’re not using raytracing? I thought Yafray’s advantages were advanced raytracing features.

I don’t know where you heard that, but E.D was definitely NOT rendered with yafray at all, it’s all Blender.
