that people don't fall in that category anyways

they just re-use the result of deltarpm in /var/cache/yum to build up 
their local repos and even in that case they benefit from one time saved 
downloads - keep in mind the result in /var/cache/yum/ from which you 
can build up your local repos is the full RPM

and that is why the current implementation of deltarpm is perfect 
designed and any improvement needs to happen on a different layer

that few lines below are enough to use createrepo and build up a local 
cache without mirror the whole upstream, you just need to have one 
machine with any pakcge you use installed on it - works perfect over 6 
years including dist-upgrades *and* benefits from deltarpm in the first step

#!/usr/bin/bash
basearch=`uname -i`
releasever=`rpm -q --qf "%{version}\n" fedora-release`
for g in `ls -1b /var/cache/yum`
do
  if [ -d /var/cache/yum/$g/packages ]
  then
   echo "/var/cache/yum/$g/packages/ > /repo/cache/fc$releasever/"
   sudo mv --verbose /var/cache/yum/$g/packages/*.rpm 
/repo/cache/fc$releasever/ 2> /dev/null
  fi
done
/buildserver/repo-create.sh

everybody can disable it with whatever action
so it has to be enabled by default to save network ressources

99% of people don't realize or know anything about nor do the update 24 
hours a day packages and so the rebuild time is not important
