Like all system administration, there are a lot of corner cases which come
up when you have nearly the same repositories. It was nearly a daily
occurence in #epel and #centos-devel of someone, somewhere having a problem
with DAG and EPEL even with the appropriate priorities. The more overlap of
the package sets, the more likely something would break in a way you only
found 2 to 3 days after you updated.
There is also a level of system administration skill to make it work
seamlessly which we forget. Most of the people running into issues were
people who had followed someone else's advice in an irc or mailing list but
did not really understand what priorities or similar tools did. People who
do know tend to also have test systems and roll out methodologies which are
second nature versus 'yum -y update' cron jobs on a fleet of systems.
