Hi Jon,
this is more like a security mechanism to prevent YUM from removing
dependencies in a very unexpected and unattended way.
>From my experience I have already tried to achieve such thing: I wanted to
get rid of sendmail but this also deleted critical packages such as cron
(!). Using RPM prevents this to happen by forcing you to explicitly adding
any package depending on your undesired package to the "absent" list.
