I'm pretty sure we could do that. But dealing with ublk is complete pain especially when setting up and tearing it down all the time for test, and would require a lot more code, so why? As-is I can directly add this to xfstests for the much needed large file system testing that currently doesn't work for zoned file systems, which was the motivation why I started writing this code (before Damien gladly took over and polished it).
