Server puts user data and system data into separate filesystems. In case of filesystem issues they don’t affect each other, you can format each independently from the other. You can umount the user data while doing critical system maintenance to protect user data from any unintended change. 

„Less“ would be putting everything in one *filesystem* separating them not at all or use a pseudo-separating filesystem like BTRFS. Its „subvolumes“ are by no means independent from each other. These are just kind of „enhanced subdirectories“.   

Of course, in some cases this strict separating strategy might be an overkill. Obviously, workstation WG considered it an overkill for desktop computers where in most cases there is only one person working on it and owning all data and in (seldom) case of data loss there is only one person affected and not a bunch of different users. And on Servers it could be an overkill in some cases. During installation, therefore there is the option to switch to another filesystem type. You can even easily introduce a BTRFS filesystem later, when there arises a need for it. 

I’m writing a Server documentation article describing those options.

No, that’s not a separation but a restriction. :-)
