I think part of the reason develop by inspection by dim green light late in the process "works" is... Yes you are exposing the film a little... but you aren't developing it that much longer. So the grains you exposed "to the point of being developable" with the green light, aren't developed for very long.
My understanding is that the film is desensitized to a degree by the development. Your idea is interesting though, Bill. Have you read about this anywhere?
