It's tempting to think that it's useful to have every package under the sun. But in reality it takes very little time to install an application when you need it. When your system must absolutely update (as happens often in arch when a new install forces a library update but that makes some of the installed packages incomparable), the last thing you want to do is be reinstalling packages you don't even use. If you don't use it, kick it, and its dependencies too. You'll shorted your update time, and get back to work quicker when that update is critical either using the system generally, or to your current task.
