I vaguely recall from somewhere that if a scanned target image, such as

yup, you have it right. Nearest Neighbor doesn't create all the intermediary

But you'll lose the values of pixels that aren't sampled. Technically
it's better to use bilinear since then you are sure to use all the
pixels in the bulk of the patches, although yes, you loose the
ability to get the ones at the edges, but they are likely to
be discarded in any case.
