I thought they _originally_ intended for servo to perhaps someday be its own thing; I had this impression specifically because I think they had at some point aspirations for servo to have a stable embedding API (to let other applications use it as a rendering engine). Of course I don't think that's the case anymore.
There was explicitly never any plan for Servo to be a product on its own. Note that this does not mean that there was an explicit plan for Servo never to be a product.
