No offense taken here.
Seeing as most responsible breeders begin placing their pups at 12 weeks, give or take, I'm sure many have concerns for the pups undergoing a surgical proceudre at such a young age and small size. I do agree with you however that the non-standard dogs that are not of breeding quality should be s/n and/or NOT bred. I question the motivations and ethics of any breeder who lets a pup go full registration, no questions asked or who doesn't take the neccessary precautions to ensure the dog is NOT bred.
