I totally see what you're saying, but I am on very limited bandwidth and
I would love to be able to use updates-testing.

I'm not sure what you mean by resurrecting all old releases.  Deltarpms
can only go in one direction (unlike diffs), and yum-presto saves the
final rpm in the same location yum would
(i.e. /var/cache/yum/updates-testing/packages for updates-testing).
