As Lennart said, it doesn't seem to be a goal. However, you can make a
system work without just fine without fstab (I run such a system).

Why does / need to be remounted? Simply mount / with the correct options
from initrd.

If you don't need initrd, a simple oneshot service with
 ExecStart=mount -o remount,rw /
should suffice, or, as Lennart said, a reload of the -.mount unit.

fsck prints a warning if fstab is missing. It's annoying, so I created
an empty /etc/fstab on my system.
