Is this still worth trying to get in 5.0? There were not many comments on v4, other than a compile fix I need to squash in and Kashyap asking a question on qemu-img convert behavior that I still need to double-check, or at a bare minimum add iotest coverage for. But depending on the urgency to get this in now, vs. delaying the deprecation clock for 4 more months by starting it in 5.1, determines how much effort I need to put in getting a v5 out right now.
