I appreciate you pointing out that "pre-provisioned device key" is
effectively identical (regarding security and tracking concerns) to a
"device serial number", since it may help participants better
understand the real privacy risks being proposed here.

I think a certain perspective is being lost here.
Firstly, device finger-printing is already being used - by third-party cookies that users do not even know about, and by DRM clients that necessarily have to finger-print the device (flash cookies !!), among others. So, I do not understand why there is so much talk about privacy – particularly when the requirement is that the user grant permission to use that key. Mark is right – it is a user's choice. It is a necessary information for the service to be provided.

Mark is also right that privacy is a business issue, not a technology issue.
