First-class modules without higher-order ones would imply (or at least I
meant that to imply) that you could not make functors first-class, i.e. you
only would have first-class structures. Wouldn't defunctorisation still be
applicable in that case? (Of course, monomorphisation would break.)

Yes, I reckon.
