New feature, improvement proposal
As empty values/null values cannot overwrite explicit values (set on a higher level, e.g. in https://github.com/apache/maven-parent/blob/f45ad57d911563c60eb3f1006a8b638c929d12d8/pom.xml#L1175) due to eclipse-sisu/sisu-project#167 there should be another boolean parameter to explicitly disable cloning (true by default).
One cannot set in the pom.xml the plugin parameter https://maven.apache.org/plugins/maven-invoker-plugin/run-mojo.html#cloneProjectsTo to a null value.
