Don't forget the bonus: all your forum accounts can be linked to your google account, just in case you didn't use your gmail as the email address.

Self-destructing cookies is a solution

Not if Google has collected enough other identifying information about you to determine whether or not you're a robot.

In any case, I wouldn't mind if sites stopped using recaptcha.
