I'm not sure what your random quoting of low-quality comments in
kernel code is trying to prove here.

Any device that does not support the LBA/sector size correctly is
not support by Linux.  We could in theory quirk it in the driver,
but for that we'd need to known the vendor/model and a good argument
why we can't fix the device reporting, as this should just be firmware.

Secrecy is not going to help with that.
