Hi everyone! The docs (https://docs.djangoproject.com/en/2.1/ref/models/querysets/#iterator) state that the
use of iterator() causes previous prefetch_related() calls to be ignored > since these two optimizations do not make sense together. I am wondering, if this is still true with the introduction of the *chunk_size* parameter. Having only one additional query per chunk could heavily reduce the amount of queries per batch.
