I'm a little surprised about all this activity.

I though the conclusion at LSF/MM was that for Linux itself there
is very little benefit in supporting this scheme.  It will massively
fragment the supported based of devices and applications, while only
having the benefit of supporting some Samsung legacy devices.

So my impression was that this work, while technically feasible, is
rather useless.  So unless I missed something important I have no
interest in supporting this in NVMe.
