Maintenance Free Crankcase Breather?

[Billdozer2]

Anyone see this? Looks like the bulletin came out last October. I don't know how to link the bulletin here, so I just copy and pasted it. The bulletin number is TSB150147. Got it off of Quickserve. Curious what people think. Good idea? Or hogwash?
