I've originally implemented that option and the Base packages and
dependencies are explicitly exempted.  This is not an option to allow
you to create broken installations, mind you.

I use that option to make sure that whenever I remove packages from my
install (or downgrade them), the clients pick the exact set of packages
up that I give them.  It's also used to shrink installations (i.e. from
a developer installation to user) without leaving lots of cruft behind.
