No more deltarpms by default

[Gerald B. Cox]

Bandwidth may be growing faster, but it started way behind processing
power.  It hasn't caught up.  The current definition from the FCC for
broadband is 4Mb.  They are working to increase it, but that hasn't
happened.  Carriers are looking for ways to throttle traffic.  Your
assumption that everyone has great amounts of bandwidth available is
erroneous.  You've also got it backwards.  Deltarpm is the default.  If you
want to change it, you need to convince the Fedora community.
