I'd really like to hear from the users. Because really, either they
should use a proper file system abstraction (including zonefs if that is
all they need), or raw nvme passthrough which will alredy work for this
case. But adding a whole bunch of crap because people want to use the
block device special file for something it is not designed for just
does not make any sense.
