I haven't seen such files myself, but that would be my guess as well.
The larger issue is that the OpenSlide API doesn't provide a way to
refer to more than one focal plane:
so even if we added support to the driver, there would be no way to
exercise it. This limitation affects several formats and will need to
be addressed at some point.

That would be very helpful.
