Question How does Plesk handle OS updates?

Plesk Obsidian Version 18.0.59 Update #2,

Hi
This is a general question - I am trying to deepen my understanding. The question does not relate to a specific bug.

I understand that Plesk (if enabled) uses Yum to get system updates. This system may also update third-party components e.g. Apache or PHP. However; it seems it does not update the OS kernel. Plesk components are installed/updated separately through the installer.

So as I understand it the OS updates might be "software enhancements". Perhaps? Looking through a list on the RedHat site an example of an enhancement might be how SSL Certificates are managed. But; if the underlying OS changes, how does Plesk keep up to date with that e.g. take advantage of new OS enhancements and/or not break if something changes?

Thanks -
