Good question. I probably haven't explained it well enough, but yes MTD is needed. If we ever want to get off of Samsungs kernel we need to ditch STL and we need to get rid of it now. It's slow, inefficient and it's proprietary (which I normally have no problem with being an avid Windows user), however in this case it being proprietary is a pain. We have no source code for it which means the kernel modules can't be recompiled for a later kernel version, which in turn means we can't use a newer kernel.

MTD is far more efficient than STL, and I don't say that because I'm like 'herp derp anything that is mainline in Linux is the best', I say that because it really is. STL works in five horrible layers for interfacing with the hardware: Data -> STL (proprietary) -> BML (proprietary) -> TFSR (open-source) -> OneNAND, whereas MTD only uses three layers: Data -> MTD -> OneNAND.

By cutting out all these other unnecessary drivers (TFSR and BML), we theoretically could get faster IO speeds on our phone. The OneNAND is an excellent NAND technology, it's just held back by Samsung being morons and not making a single driver. If it was just TFSR that we used or just STL and they could handle everything by themselves, then I wouldn't be complaining, but they had to add two more pointless layers to handle bad sectors and it ruins the whole system.
