Qemu 8.1.0 will add discard_no_unref option for qcow2 images. When this option is enabled (default=false), then it will no longer unreference clusters when guest does a discard, but it will just free the blocks (useful for incremental backups for example) and pass the discard to the lower layer. This was implemented to avoid fragmentation within the qcow2 image.
