Yes, it's work in progress that has been stalled a little. See:

details.

Oh that would be very welcome. A "secure" filesystem sounds really good,
especially if it's fast as XFS is :-)
I'd implement it everywhere immediately as soon as it's available. Will
existing XFS's be upgradeable in some way other that backup/restore?

checksumming inodes and btree nodes means larger data structures for
those, so no there's no upgrade path available.
