He will. :-)

iXsystems is happy to sponsor this work as it directly benefits us as well, and I’ve been very happy to see you engaged with the review process.  With any luck, Chris will be able to finish this and then unwind his stack back to the point where he can finish wiring up NFS quotas to ZFS, which was the original feature request that started us down this path.
