All nodes can still have equal privilege. Data must originate from somewhere, that is a seed node. And supernode is, or at least was when I studied CS, basically just a more connected node. That said, I agree, a project like this could do with a more formal and structured definition of goals.

I have not read the entirety of their documentation in great detail, but what I did glance over, I did not see anything particular special about seed nodes other than they host and serve projects. And obviously there is a bit of plumbing required for that.
