This flag is programmed to 0, if a complete page is written and tells the
ECC, that the data can be read with ECC.

Not yet, but we are going to implement this. We definitly will use byte 5. We
detect the bad blocks marked by the manufacturer, which we never touch again,
and mark detected bad blocks at the same place.
