I think the point here is that you don't _have_ to _reboot_ except to use a newer kernel. The actual programs (or services) can be restarted as needed (or not). Now, some updates will force a service restart (if the service is running) because of some dire security issue or incompatibility between versions (e.g. some selinux updates, some journald and systemd updates, etc.), but it's not that common and only done if there are significant reasons to do a restart and the service restart will be logged. After a significant number of updates, it's probably be a good idea to reboot just to ensure you are using the latest kernel and that any services that were updated have been restarted. How and when that reboot cycle happens is completely up to you. You can ignore it all together if you wish. Fedora is a very dynamic environment and updates happen a LOT. It is, essentially, the development environment for RHEL. RHEL (and thus CentOS) are more stable and have relatively fewer updates over any given period of time--and then they're generally security related. For stable, production platforms, use RHEL or CentOS, take the updates and schedule reboots. With Fedora, you're on the "bleeding edge" and you WILL, on occasion, get hurt (I guarantee it). It's sorta like Santa told Ralphie in "A Christmas Story"...
