I don't know why you are down voted, because it's an interesting point.
I often use the term W3c Web Components to differentiate from JavaScript components that use other APIs.
I know that Web Components are a recurring topic in W3C meeting agendas. I am not aware about parallel fast track discussions in WHATWG, but that makes sense.
I think there are already two Webs (simple and complex) and Web Components are actually a good way to create progressively enhanced websites that work well in both.
