There are reasons to do system administration from a GUI, especially
if decent GUI applications exist for common tasks.
The trouble with doing so, I have heard, is there are features
in X that give a program that is talking to a window on an X screen
to place input in another window ... this apparently was originally
a feature whereby neat GUI things could easily be implemented,
but it the other window happens to be a root login, it's
a security nightmare.
I believe window managers may use this stuff.
By the way, I don't know about now, but 15 years ago, the window
manager didn't even have to be running on the same magine as either
your screen or any of your applications.
