I don't see the use of that either. The work has sone use in figuring out what the technical differences are between the old and new, and to review differences to see why the exist and if they matter. The only way around that would actually be remotely useful for doing odd debug checks would be the ability to run the old stack drivers under libata. Even then it would probably be far simpler to move differences over one by one and test them so as to understand what is actually going on and fix a bug. The old drivers contain a fair amount of crap, magic and gueswork so a good deal of human analysis and testing is needed to move any change around and prove it's real and valid not guesswork and fudging.
