My recollection was that it was Microsoft deciding to turn this flag on by default that led to it being ignored by Google. I.e. Microsoft saw a chance to use it against their biggest rival, diluting it in the process and gaining nothing.

I think there's an argument for trying again but requiring an explicit choice. And then give it the force of law.
