Fair enough, but how do we explain the second paragraph of the leading comment on the function then?

 * Note we don't check that the extents exactly match since a valid
 * copying operation is to either add sparseness (qemu-img convert -S)
 * or create a fully allocated target (nbdcopy --allocated).

I think it directly contradicts the assertion. That, or I don't understand the comment at all.

(It's from commit 2d0954dd6431, "New filter: checkwrite", 2020-12-22.)
