The devil will be in the details, however. Google could screw it up by, for example, requiring publishers who allow CPC site targetting to also allow CPM site targetting

I agree that the devil is in the details, although I don't think CPC contextual site targeting and CPM general site targeting are necessarily in conflict with each other.

It's possible that contextual site targeting won't be as important as the ability of advertisers to see where their ads are running. That knowledge, combined with the new unlimited domain filter, could be bad news for publishers who deliver low-quality traffic to advertisers.
