I am nobody qualified to interject with any sensitometric evidence. Only intuition. And I'd tend to believe a lot of picture information and local contrast has been pushed up or over the shoulder. And the only hope would be undervelopment. Trading one bad thing for another in this case is the only possible hope. The first remedy that sprang to mind was pyro, but I have no experience with the stuff to back up my thought. However, "normal" development is something I'd discount immediately and close my mind to it.
