Correct but if they do mirror delta rpm's they would get higher I/O
since clients would be fetching a series of smaller packages instead of
bigger ones. There is also some additional processing required on the
Fedora infrastructure to generate the deltas and on client side to build
the full RPM package from the deltas. So it is a trade-off.
