"Google is proposing a solution that offers more privacy from the extension, and it seems very similar to what Safari has done (and which is very widely viewed as a great design)."
It would only provide more privacy if ad block extensions go solely with static lists of uris. If they want to retain features like right-click block, or allowing users to customize the list, static blocks don't work.
These changes do nothing to inhibit the ability to log/store/etc requests anywhere you want as an extension author. They are only removing the ability to cancel in flight requests.
What's your source that the Safari ad blocking approach is viewed as a great design? Everything I look at shows it was a regression in effectiveness. Certainly the various adblock authors weren't thrilled. How well, for example, does it work with YouTube ads?
