No vendor wants to sell raw flash without wear leveling that's exposed to software. It's a significant liability from a warranty perspective, as the manufacturer has to potentially replace the device when the user make a mistake or uses poorly written / buggy software that wears out the flash out prematurely. The one place where that does make sense is for hardware devices using SoCs that include interfaces to directly attach NAND flash, but in that case it's usually the hardware vendor that provides the software, leaving random end users out of the loop.
