i'm talkig about *any* disk device here.... a partition table has never
been a pre-requisite to put a filesystem onto any disk device.

i dd around (partitioned and unpatitioned) filesystem images all the
time, be it to NVME, SSD, rotary HDDs, SD cards or USB sticks ... you
can just format any disk (as long as the filesystem can handle the size
indeed (i think fat16 on a 2TB drive would fail actually)) without
partitioning it and can mount/access it trough a device node in /dev.

the kernel doesn't care, the filesystem doesn't care ... the physical
media doesnt really play a role here either.

you technically wouldnt even need a partition table for booting from
such a disk as long as it is an old BIOS based system (UEFI indeed
needs the EFI partition) by simply using root=/dev/yxz 

it is admittedly cleverer, cleaner and more common to have a partition
table but there is absolutely no hard technical requirement for it.
