MLC is different from SLC in that:
1. block erase count is less
2. write speed is slower
3. read bit error is more often

I think file system can do little effort to defeat 1 & 2.
As to 3, stronger error correction code other than ECC maybe used in mtd layer.

And I'm using YAFFS on an MLC NAND flash, and it works well.
