In Helm versions <=3.20.1 and <=4.1.3, a specially crafted Chart will cause helm pull --untar  [chart URL | repo/chartname] to write the Chart's contents to the immediate output directory (as defaulted to the current working directory; or as given by the --destination and --untardir flags), rather than the expected output directory suffixed by the chart's name.
