In this case, I would expect NOIOB >= atomic write boundary.

Would it be sane to have a NOIOB < atomic write boundary in some other
config?

I can support these possibilities, but the code will just get more complex.
I'd be tempted to simply not support the case where NOIOB is not a
multiple of the atomic write boundary for now and disable atomic writes
with a big fat warning (and a good comment in the soure code). If users
show up with a device that hits this and want to use atomic writes we
can resolved it.

Fine by me.
