Hmm, ok I'm not sure if that's true or not. I was just noticing (again) 
that KDevelop already does this sort of palette hacking (and /on 
highlight colors/, no less). I'm not sure if it is forcing a separate 
style instance or not (if it isn't, it should be for the previously 
mentioned reasons). However, the reason I notice is because KDevelop 
doing this already causes problems. The issue remains that you are 
circumventing behavior in the style, which can cause visual glitches /in 
the style/. In fact, I'm going to go report this to KDevelop now.
