Should be soon. The main patch is now in OpenZFS, but hasn't yet
been pulled into FreeBSD. The one that fixes a weird case where you
can create two attributes with the same name (one done when "xattr=sa"
via setextattr(1) and the other done via namedattr when "xattr=dir") is
now a pull request.

Hopefully both patches will be in 15.0.
