I find it useful to be able to track what mirror contributed which package
and version.  But as for general usefulness, I can't comment as I've long
since forgotten the details of the original design intent.  However, I will
point out that separating mirrors into different directory trees isn't a
peculiarity of 'setup.exe'.  'yum' shares this basic structure.  Perhaps
other installers (apt, smart, etc) do as well.  I didn't experiment with
those.  But I don't think the cache structure by it's very existence and
usage prohibits other semantics.
