This hasn't been true for a very long time. Juniper router's have rollbacks, commits and revisions:

Except Cisco doesn’t have a commit feature in any of their OS and the rollback feature is not implemented everywhere as well - NXOs doesn’t have it for example. Still, it’s better than ‘reload in 5’ that we had to use back then.
