I've never had a roasted neck, but I can say that none of the non-roasted necks that I have are like that. They all look like a perfect fit.
I remember having a neck once with a gap like that, and like @Intune said, I could feel it, and it did bug me. So I think I have to be on the side of Fender can do better.
