Just did the CDV delete and the actual removal was easy! Getting the car jacked up and safely on stands was the biggest pain in the a$$. Make sure you properly clamp off the hydraulic hose leading into the CDV so you don't lose too much fluid. Mine slipped and dumped a few ounces all over me and the floor making the bleeding of the line a long process.
10 minutes to safely jack & support car.
2 minutes to clamp line, remove clips, remove CDV, re-install the line and re-install the clips.
30 minutes to bleed the air out of the line.
5 minutes to bring the car off the jacks & stands.
Result: much improved clutch response during normal driving, especially starting in 1st gear and shifting to second.
Was it worth it? YES.
