I think Eric's point is that dropping oldstyle in qemu-nbd isn't really a problem because nbdkit has no plans to drop oldstyle. So there will remain a path for very old clients to keep working (whether using nbdkit natively, or using nbdkit to proxy to qemu-nbd). Eric's example used the more complex proxy case. By contrast the nbdkit native case is very simple: nbdkit -o file disk.img (where the ‘-o’ flag switches to oldstyle protocol).
