Clearly it was due to genius!
I'm going to have to disagree with you on that one. I'm genuinely curious, though. It seems like they kept that functionality for all previously supported file types except .swf. They allow it to work in CS6, and loading a project into CC that you've put through this process in CS6 works just fine - you just have to have CS6 available to Import to Stage that .swf in the first place, which is ridiculous.
