It doesn't just save 500 bytes of transfer, but DNS lookup and
connection setup entirely. Since we know that these files won't change
for a full day, this should be avoidable.
For example, if I am bringing a new server online and my favorite mirror
is unreachable, I can still get package lists, and install any packages
that are already cached (which I should rightly be able to do).
