It would also fail the letter of the definition of independent we used in the CR exit criteria for HTML5 and HTML Canvas 2D Context:

Independent - Each implementation must be developed by a different party and cannot share, reuse, or derive from code used by another qualifying implementation. Sections of code that have no bearing on the implementation of this specification are exempt from this requirement.

This definition of independent is modeled on the one used by other WGs such as CSS, so I think it's generally understood that way.
