I wondered a little about this too. What about customized things? The thought crossed my mind about coloring and such, but I more mean like polished parts. Would people that had polished various things to try and improve performance get those parts removed and stock ones put in?
I wouldn't think so, if it's a stock part that's just polished. The original finishes tend to wear off through use anyway, I don't see why they'd swap a polished stock piece out with a regular stock piece unless it was broken. But I haven't had to send mine in for repair, so I don't really know. It just makes the most sense to me.
