wic allows the user to create disk image and reference each created
partitions via its partition UUID.
squashfs does not support filesystem UUID but it does offer support for
partition UUID.
$ lsblk -o NAME,FSTYPE,UUID,PARTUUID
NAME FSTYPE UUID PARTUUID

Removing this constrain allows a user to create squashfs-based rootfs and boot
from it with such kernel argument
'root=PARTUUID=7d46da2d-29cc-4d5a-9e39-d0381c4abb0c'
