The proposal is a new tool to manage dm-thin devices, not to rewrite lvm.
I would hope the tool is nothing at all like lvm, but rather "thinsetup"
in the tradition of dmsetup, cryptsetup.  I think it's a great idea and
have wanted such a tool for years.  I have a feeling that many have
already written ad hoc thinsetup-like tools, and there would be fairly
broad interest in it (especially if it has a proper lib api.)
