No not really, my point is that people have a distorted and exaggerated view of BVR. 100 miles was beyond even the max range of common missiles and even with modern missiles like meteor it's completely unrealistic to fire at that kind of range. Provided that you have detected and are able to track the target at that range.
I don't know if modern planes will have to resort to guns but WVR dogfights with IR missiles are more likely than destroying F-35s at BVR ranges.
Why would they sell? That would create a competitor that could easily expand into other markets and take away that user base as well.
