The impression I got was that he was going to store his data in a git object database and that the files would be virtual in there. It would be like the .git directory without the working files on disk. It's all just conjecture until his code his out. Regardless, I would think that some applications are simple enough (store few enough separate objects in the file system) that the issues you cite are not likely to cause a problem.
