I'm sure the breeders are less concerned about socialisation than 'pet' breeders, but that's only natural given their breeding interests
If the breeders are selling puppies to pet homes then they should be doing all they can to prepare them for that environment.
I hate to be negative but personally I would walk away from the situation as you've described it - I'd be unhappy about homing an 11 week old pup that has never lived indoors or had much human interaction, it just seems too risky to me. I'm sure others would disagree but that's my opinion, for what it's worth.
I'm afraid I agree with Colin - I brought Molo home at 10 weeks (due to a prior family comittment I was unable to bring him home sooner).
He lived in the breeders home with her other dogs - cos he was the last pup he curled up in front of the TV each night with the family, so they were a bit upset when he came home with me
Despite this, there were things he did miss out on, and which I had to put a lot of effort into to ensure he was not disadvantaged; he was a nightmare in the car at first, as he had only been on one trip with the breeder (to the vets for his first vaccination). I planned a comprehensive socialisation schedule that involved the whole family; normal life kind of got put on hold for the first 4 or 5 weeks, as we travelled on buses, trains, visited farms, the beach, invited visitors round and went to fun fayres and village shows
Interestingly, although he is a very laid back (show) cocker there are still things that make him jumpy (such as bath bubbles
); which is all the more noticable because he is so chilled the rest of the time
If your pup is from a litter whose sire and dame are selected for working, then he is far more likely to be more alert and sensitive to his environment than my dopey Molo; which means that the lack of early socialisation is likely to be more of an issue
I understand that you have your heart set on this pup - but when you consider the fact that they the litter have been selected to be workers, and socialised with that in mind by the breeder, then the expectations you have of this particular pup to settle in a pet home after very limited early socialisation may be too much
