They're of no consequence to me and they don't own this bike so.
Here's mine.

Even before the EPA got involved, there were PCV valves in cars to vent the positive pressure in the crankcase . It makes sense to vent the fumes somewhere to prevent damage to the engine.

Of course. Couldn't agree more and the best place to vent this pressure is to atmosphere. Not the combustion chamber. Best for your motor anyway which the EPA could care less about, btw. Did you think I wasn't venting?
I vent from the cam chest to under the frame. Breather bolts have been replaced with solid bolts. The umbrellas in the heads are no longer functional. They've been replaced with one krankvent you see under my cam cover. It closes almost instantly on upstroke not allowing near as much excessive cc pressure. No mess of hoses dangling from the heads is an added benefit. This is how the venting used to be.

Your system looks best to me but it sure is intimidating -- way above my pay grade. If I had your skills I would definitely do it your way. I just have the hose running down with the others in front of the swing arm and without a filter or can. You don't notice it unless you look underneath the ham can and then you only see a few inches of it. Fortunately, the air filter housing is black and the hose is black and the frame is black.

I'm not going to blow smoke up your ass and say it's the best thing to do for everyone because it's not. It does require drilling and tapping a hole in your cam cover for starters and you need to be aware of possible unintended consequences. For me and others here it was a good move and worked out great.

I understand and I agree. I know my limitations and this is why I designed and got the parts for an adjustable brake pedal rod for my 2005 Sporty with mid-controls which had a pedal that was about two inches too low. I took everything to a local machinist who did a far better job than I ever could. It was a modified NOS chrome brake rod with a stainless turnbuckle in the center and stainless jam nuts. Beautiful and it works perfectly!

It's the best place to vent but due to some wanting to see absolute proof that stock isn't the best, I'm done arguing the point. They can run the cheap umbrella contraptions in the heads that leak air like a sieve back in if they feel it's a necessary design. I know it's not and just causes oil foaming and high temps and oil coming out the breathers. The pistons cause enough pressure on their own for scavenging. Adding outside air, any air, is not necessary and not good. Period.

I agree with you but I would like to learn some more about umbrella valves. This forum is the first place I've heard of them and would like a description, picture, drawing or whatever anyone has that explains their function. Do they force the Positive Crankcase fumes to the breather bolts? Teach me, Obe Wan.
