The drive can infer that the LBA hasn't been mapped, since it won't be present in the FTL, there is no need for the OS to inform the drive of this.

How could the drive know? TRIM commands are the only way to "free" a sector/block for writing. The drive might have been tested during setup, so the block might not be empty any more.
