It is not much that will in practice be retained. Keeping the whole kaboodle (including uid and gid) makes git suitable for archival purposes on Posixy platforms. The current code offers just a single policy (suitable for distributed development) with regard to what it maintains and stores (well, actually two: you can tell it to ignore the execute bit from the file system), but it would be reasonably straightforward to extend this with further policies.
