As far as I remember, using "|" cannot not solve all problems. For example, if you need the main GUI component, and the corresponding opengl component. This is the reason why I had to make several packages. And it allows the user to explicitly choose which GUI he wants to use, whereas the "|" feature can lead to a bad choice from the system packager.
