It's difficult problem to solve. If we do put it in the filesystem, we need some way for the filesystem to know how the NAND behaves. Otherwise the lowest common denominator dictates and nobody gain anything. With this in mind, I don't see why the disk cannot handle this in the firmware. As long as there is enough free NAND on the drive, it can manage wear level and GC just fine assuming that it gets TRIM commands.
