I've already known that currently systemd can only add .device units
from udev. My question was "Is it suitable for systemd to add supports
of loading .device units from .device unit files in
/lib/systemd/system ?"

What I expect is something like:
My_machine.target.wants/dev-sda1.device <or generate from /etc/fstab>
My_machine.target.wants/dev-sda2.device
...
My_machine.target.wants/dev-tty1.device
