Oil in the intake on my '16 Duramax... is a CCV reroute worth the hassle?

I took my intake boot off today and it was covered in this nasty black sludge from the CCV system. I know the Duramax CCV system is designed to dump that back into the intake, but it looks so gross. For those who did the reroute, do you get much oil dripping on the driveway? That's the only thing keeping me from doing it.
 
If you don't want to deal with the hassle of emptying a catch can every oil change, just grab an open reroute kit that vents to the frame rail. I ran one on my last truck for 80k miles—zero issues, zero oil in the intake, and the driveway stayed bone dry because I used a long enough hose to let it drip way back near the rear axle. It’s a 15-minute install if you get a kit with the factory quick-connect fittings. Save yourself the headache of future intake cleaning and just vent it to the atmosphere.
