 Why is there no reason to have a hash? The download helpers will indeed detect
failed clones/checkouts/..., but they won't detect a failed download from the
PRIMARY or SECONDARY site, e.g. if a user configures a bad PRIMARY site that
always gives you a landing page rather than a 404.

 Also, a second reason to have the hash is for "security", to protect against
MITM attacks. git with a sha1 will protect against that, but not if you give it
a tag. And svn, well, I'll leave that as an exercise for the reader :-)
