Carrier groups aren't hidden from powers with reasonable satellite constellations or radar / sonar groups. They're hidden from Iraq or Saudi Arabia or the journalists at the New York Times. And my first thought was like your's, but I came to think that between subullites, refined SIGINT analysis for surfaced subs, and the few locations on earth we know manufacture these things I think it's going to be more possible to follow submarines than you're making it out to be. Humans have to disembark these things, at least if we want humans on them. Even in a future where all subs are autonomous they'll still need to be manufactured somewhere and will still require supply (re)provisioning. But I'm open to changing my mind on this if you have a special insight.
