That's really quite significant, since it changes the feature to one which could allow changes made to interfaces to adversely impact existing clients of an interface without those clients changing a thing. I was excited by the description of the RFC, but I was imagining something more like how Java does it. Personally, this limitation (or rather lack of it) is enough that I wouldn't support it and I'd urge anyone who can vote to carefully consider the implications of the implementation being proposed..
