Unless there's an obvious error such as overlap with ECC or a bad block
marker, there isn't really a right answer (except to the extent that
you're wasting bytes) -- but it's important that everyone agree. So
the answer is basically, "which compatibility would it hurt more to
break?"

That said, the U-Boot ones make more sense to me in terms of not having
strange missing bytes.

Yes. Bad block markers are at offset zero except on 8-bit 512b-page
chips.
