Especially since Puppet/Salt/Ansible does that part for you. Apply the "web server" class to a node and there is nothing to forget as the relevant config templates are applied both to the monitoring system, the backup runner, and anything else. Configurations that live in a database somewhere is much harder to manage as they have to be set by a config running which needs to be written and maintained.
