This is important for a mass-airflow car, but does not matter on a speed-density car, since the airflow is not metered.
As for keeping the PCV system from pressurizing the crankcase when you're using forced induction, I might suggest doing how at least some factory systems do it.
Then route both valve cover openings to the the intake tract ahead of the blower.
Extra points if you place a slash-cut tube in the inlet pipe oriented properly of course.
I wouldn't let examples of laziness or bad engineering dictate what's best.
