Erasing NAND bad blocks?

I suggest to disable retiring blocks that failed ECC on read. I see it happening
during power cycling. YAFFS leaks good blocks, e.g. disrupted write/erase
creates bad ECC and then GC retires perfectly good block. JFFS2 does not do that.
AFAIK, manufacturers suggest discarding only blocks that fail on write.
