Thank you, both (disturbing) W3C draft and EFF position were an entertaining read.
What I find the most disturbing is that it's going to be way harder to opt out of this than to opt out of cookies (which is essentially a hack anyway), and also governments will take some years to regulate this approach, which is a bummer.
Let's see how it develops as far as players like Mozilla are concerned... Maybe they won't implement the spec?..
