   And why not preserve the choice of the admin to make /lib, /sbin,
/etc and wtf mountable partitions? There should be no limit to liberty,
should it? Actually you have this liberty, which is to not use a distro
and devise your own FSH.

    But if you use a Debian derivative, or whatever distro, the scope
of the package manager is the whole filesystem, with the major
exceptions of /home and /usr/local. And breaking it in separate
partitions for the sake of security is an illusion, because a failure of
one partition would cause the package manager to detect such
inconsistencies that it would just refuse to work.

    The only reason I can see to use separate partitions is when you
want to use different filesystems. For example, you can install any
fancy filesytem of your preference on /,  but use ext4 on /boot to make
Grub happy -- make it large because of issues with dpkg when it's full.
Of course /home must be separate whenever possible; it contains a lot of
junk, but also presious stuff. All the rest can be reinstalled with a
memory stick and a network connection.
