Sorry this didn't receive a timely response. Deleting disks through virt-manager uses libvirt's storage APIs which I don't think will grow any awareness about if they contain snapshots, or say if a VM is even using the disk, similar to how 'rm' isn't going to tell you what depends on the file. This could be something instead that virt-manager warns about, please file a bug against virt-manager if you're still interested
