Yeah I suppose I could eliminate the stock pcv altogether, but i think my current design may satisfy the purists out there. Massacre, you doubtless run a catch can from those valve cover plates, yes? My design puts the barb's port at far upper exhaust side to limit oil mist, and I am merely running a modified (ie: poked thru) fuel filter as catch capsule, rather than a big can. No problems yet! And like you validate, the valve cover pulse works great. It also seems a really convenient place for making your other case venting mods. I had been making them with plastic barbs and any odd rubber seals I could find, but it works so reliably that I upgraded to this design for simplicity as well as durability.
