As currently specified, it's not even testable for the UAs, since there 
are no testable normative requirements.

I am not going to persue this particular issue. In my opinion the current 
state of the spec makes it useless and the feature will never be properly 
implemented (since indeed there is not even a definition of what it would 
mean for it to be properly implemented), but the success or lack thereof 
of this part of the specification is not my concern.
