安装X不需要X-Window-System 了？

安装某个软件自动把X-Window-System 干掉了，X居然没挂掉，看X-Window-System 的描述：
transitional package for Debian etch
This package is provided to smooth upgrades from Debian 3.1 ("sarge") to
Debian etch. It may be safely removed from your system. It depends on the
xorg package which is the new metapackage for installing the X Window
System in Debian.

难道X-Window-System 不再是必须的？

有些包是虚拟包， 你安装它时，它会装很多“依赖”它的包， 但是你卸载它， 并不会卸载其它实际上其作用的包
