I cant see how a bridge doctor would be of any great benefit in a new guitar, as there wouldnt be a problem to correct.
Breedloves have them from new because it allows the guitars to be constructed with thinner tops ,so thin that they would collaspse without the bridge doctor reinforcement.
I suppose you could make an arguement for putting a bridge doctor in a new guitar, along the lines of that it was a form of insurance policy against the top never moving, but thats a bit like saying Martin et al dont know how to build guitars and that tops are best constructed from laminates
