Review Comment:
> I don't think an inconsistent offset (sometimes it is empty sometimes it
is one value buffer) is a good idea. Very confused and easy to cause bugs.
Code shouldn't make assumptions because we've already documented that those
assumptions are wrong. It would be equally true for code working with imported
arrays: they may have a one value buffer.
