As stated by David Woodhouse, it was a huge mistake by UBI to not reject MLC NAND from the very beginning.

Correction: when we were developing UBI/UBIFS and upstreamed them, MLC was widely used yet we did not really know about it. So there was nothing to reject yet.

You mean *not* widely used?

The mistake is that we did not add the reject timely. When people started reporting MLC issues we were answering that UBI/UBIFS stack needs more work to make MLC safe to use, and we hoped someone would do the work.

True. TBH Boris and I also thought that adding MLC support is not a that big deal...
