"At least with the proposed scheme, adblocker extensions wouldn't have had access to a user's browsing history."
No, that's not true. They aren't removing onBeforeRequest() and friends. They are only removing the "cancel" function in it.
Extensions can still log and forward every request.
The only tiny kernel of truth here is that an extension that only asks for the declarative API permissions couldn't do that.
I doubt there will be any popular blocker that only asks for that declarative API. They still need access to onBeforeRequest() for any sort of heuristics to allow the user to add/change rules based on page behavior.
Also, separately, extensions can inject JS into the DOM. So they can do anything that Google Analytics can do anyway. Like track visited pages.
