Its because it is possible to screw a connector up with just a dremel and pollish. Taking that felt wheel to an edge in the wrong place can slightly change an angle at thats all it takes to go FA. MANY have done it.
I'm not saying I dont do it because I do and have done many for my self as well as many other.
To make a blanket statement that it CANT happen with just a felt wheel and some rouge is just plain ignorant.
