Advantage of using jffs2 for kernel and initramFS in NAND

In our system we use jffs2 to write kernel and initramfs into NAND memory. We would like to use stronger ECC soon. But new ECC format requires whole OOB area, and does not work with JFFS2.

I am not sure yet, why do we need to use JFFS2 at all. AFAIK kernel and initramfs are copied into RAM at startup, and runs from RAM. They are not changed very often (maybe few times in year for update).

jffs2 is designed as filesystem for flash storage, usually use as rootfs. There's no any advantage for using it for kernel and initramfs image.
