I'd love to, but I don't know how. David, could you suggest something, please?
As noted by drago01, this is not exactly new or specific to thinp -- a
similar situation exists with btrfs. You would have to ask the
developers of lvm and btrfs for a way to decode the magic. I don't know
any manageable solution to this problem.
