Maybe there is a reason > against that, but it should be clearly stated here. That may be a good idea if everyone uses the more efficient iter, but I thought it'd be safer to keep them separate. There are just a few import_single_range() users that expect the result be ITER_IOVEC. It will take some extra time on my side to make sure that kind of change won't break anything.
