2 node HA fail-over storage configuration possible using Rclone?

Is the problem highlighted in this thread, namely creating a Gluster brick out of a Rclone mount, related to this other thread regarding the lack of xattr: https://forum.rclone.org/t/questions-regarding-extended-attributes/10553? If so, are there any news in this regard? Will something like this be possible in the future using rclone or rather not?

Thanks for any help!
