JFFS2 write behaviour is the best-case scenario for any FTL. When the delta cache is finished, LogFS will be pretty close to that as well. Not sure if anyone would specifically target FTL. Being well-suited for those beasts is just a side-effect. The FTL is still a net loss. Without that FAT enabling layer a real flash filesystem would be more efficient.
