I just took an md5sum of every file on my system. Including things like
/var and /home that aren't part of packages. It's 13M, uncompressed.
Compressed, it's 3.5M. 

If we were really worried about archive size, an md5sum is 16 octets.
It's hard to see that mattering to overall archive size.

Have you ever met any bit changes that defeat md5? Didn't think so.
