 - always include `--ignore_force_shutdown` on the template-generation command unless the operator explicitly overrides that default,
 - always include `--test_partition` on the template-generation command unless the operator explicitly overrides that default,
 - default plugin-bearing templates to `--use_specified_plugin iscsi` unless the operator explicitly requests another plugin or the template does not use plugin selection,
+- if the operator explicitly requests `cmc-group-consistency` with one VM, allow the single-VM request and plan it without asking for additional VMs,
 - treat `cmc-systemOS` as a template that does not use plugin selection or integration-type selection, so omit `--use_specified_plugin`, omit `--integration_type`, and omit watcher integration/plugin metadata for that template,
 - use a descriptive `--build_name` without Gold Disk IDs.
