As I told you, this won't work in the NAND case.

If there's a bad block in the NAND, the offset will be incremented by
a block, and it won't be taken into account by the fastboot client,
and you'll end up writing on a block you already wrote to.

I guess the only solution is to make the storage backend scan the area
you skip so that it adjusts the skipped size, possibly extending it.
