I keep it thinking about further moving qemu-img convert to block-copy. But I don't even have a plan when to start this work. So, if we want to do something around copy_range here to prepare for thread-safety, let's just drop it for now as unused on top of "[PATCH v2 00/33] block: publish backup-top filter" (you can take one patch that drop copy_range support in backup to your series to not make a dependency). It's not difficult to reimplement it later.
Then we'll have this same conversation later. I would hope that this series goes in before yours.
