With regards to the OP's question, it specifies that it only works on squads of generic Chaos Space Marines. So no enhanced cult warriors, or chosen, or termies. It sucks, I know.
With regards to Fabius-themed armies, I would say don't. I say this from experience. I played a Fabius centered CSM army for around 3-4 months. Got around 20 games in with it. During that time, Fabius single-handedly killed more of my CSM than my opponents did (I started keeping a tally after game 3). If you roll a one, be prepared to suffer the consequences of neutering your squad when the Champ/Icon/Special Weapon guys die. Not fun.
Yes, I know that statistically you shouldn't have rolls of 1 or 6 too often. However, I have found that statistics seems to b*tch-slap you when you don't want it to. Like when you roll for enhancement.
Over-all, I found that the pro's of enhanced marines just didn't out-weigh the risk of having half your squad die before the game even starts.
