Honestly it should be an option
I certainly understand why someone would want powerful graphics in the Mini. Better gaming and accelerated graphics. People who need the power of the iMac but don't like the built-in ACD.
On the other hand, there are people like me who don't even have a monitor.
For me, low power consumption and heat are far more important than the speed of a GPU that isn't even hooked up to a screen.
