I don't want the lack of a fixed endianness on disk to become a problem. I personally don't think the use of, or lack of a fixed endianness to be that important, but I'd prefer not to change the current situation and adopt a fixed format. I use big endian systems almost exclusively, and I don't like the way fixed formats always tend to be little-endian.
