Correct.  They work, but the tools can't report the size correctly, so you
get odd results from tools that show the size of the partition.  Fixing
this requires a protocol change to use longer fields on the wire.  The new
protocol is currently being worked on.

The protocol change is not required to store files correctly in such a
partition, just to correctly report its size through the standard tools.
