I agree for the desktop/laptop/pad/ use there is no need for splitting
besides /home and maybe separate /boot if you want to use encryption.

Ok, this is exactly the part that have raised my concerns that it was
about to be "forgotten" in favour of "simplicity".
Server installs usually want to be more "free" to finetune.
Another use case is to be able to split up the system on more harddisks
to even the load on the disks.
And yet another is simply to get more space depending on hw.
(yes I know lvm exists but it's also an extra layer / point of failure
that is not always worth it)
But if this part is the "some specific usecases" then I guess I need to
start re-reading some stuff :)
