Package management in Linux is a pain in the ass. It is too easy to remove preinstalled packages and if you do so, it will be a potential failing point in your system until something happened. You need to install packages for some basic features and everyone was just install and forget. People don't remove packages after they have served their purpose. Those packages will stay in your system, occupying space and slowing up everything. The worse thing is that there is no easy way to "diff" the original system, and find out what have you installed/removed.
