From Crawford themselves:
"This not only keeps the vehicle within specs of smog but keeps the oil from coating the tops of the pistons. We all know what that does to any tune you have; it causes detonation, a very bad thing for turbo engines."
I don't entirely disagree with your general logic here, but another response to this would be that you can obtain similar results utilizing a different manufacturers product (Grimmspeed) or other methods (classic catch can). What you're suggesting is making a rule change to allow a specific part. I get that it's not a performance increase, but it's not as if you can't achieve the same functionality in a different manner.
