I don't see how it would impact Google at all. Does Google change their behavior if you include Adding a mechanism to bypass URL-encryption for actual (non-ad) external links would be easy, if someone cares about traditional PageRank-style references. Other than that, the client (possibly GoogleBot) still gets the same page content; it's only the URLs that change. I have no idea (and really don't care) if URL changes affect the "search engine optimization" games some people like to play. I'm describing a way people could actually defeat adblocking; if that method is annoying to use because of side effects, that's not my concern.
