I sort of presumed that there might be need for _some_ platform code
later on, just not quite yet, so I didn't want to be quite that
drastic. I suppose leaving it with the trivial file for now is OK, and
we can make a sweeping change down the road in case we want to clean
up and consolidate all the trivial platforms.
