ZFS project for Mac OS X discontinued

Is it a forgotten project? A fit of open-source pique? Or is it just that everyone got really busy on other stuff? Looks like Apple has just shut down the ZFS project for Mac OS X. The site for the project on Mac OS Forge reads:

ZFS Project Shutdown

The ZFS project has been discontinued. The mailing list and repository will also be removed shortly.

It's hinted that this was caused by legal issues surrounding the merger of Sun Microsystems and Oracle, which caused Apple to back away from the next-generation file system technology. After many rumors, including ZFS support that was going to be added in Snow Leopard Server, but that ended up being removed in the final version, it now seems like the saga of ZFS on Mac OS X is ending with a whimper.
