It doesn't have to be malicious for it to harm privacy, help them track users for advertising and to be anti-competitive.

The implementation details around cookie recreation don't matter if users are still being tracked. Especially bad if this lets them track you on third party sites that contain Google Plus buttons or advertising iframes.

By ensuring users always remain logged in to the browser they gain a strong advantage over other companies that track users. Users attempting to remove tracking cookies shouldn't find Google ones permanently bundled with the browser.

The intent was likely to aid convenience and avoid users being unexpectedly logged out, but combined with Google automatically logging users into the browser this is a sign that the Chrome team is paying less attention to user privacy than they used to.

Perhaps users who regularly clear all cookies will start using guest accounts instead. Myself I'm more concerned about the general trend of unexpected behavior.
