Mailchimp has changed it so that once a contact has been unsubscribed they cannot be re-subscribed.
The push sync unsubscribes contacts that are not in the CiviCRM group that is mapped to a Mailchimp audience.
To avoid accidental and irreversible unsubscribes, the push sync will be retained but changed so it no longer unsubscribes contacts.
The jobs are by default not active so should not cause any surprises if dry-runs are performed before enabling them.
