Key value FTLs have been around for about as long as FTLs. The logical block address -> NAND page forward map is just a key value store after all. It can potentially take one layer of indirection out of applications but you still have one there (the FTL). Or alternatively exposing the raw NAND and having the software manage it is another common way to go (indirection is in software now instead of hardware/firmware). When I worked on FTLs it was always a thing executives and product managers liked to talk about but didn't seem to provide incredible results and people generally didn't like using them because it was just harder / different to manage. Has that changed?
