As helm charts become used by more people and more complicated, exposing more of the underlying config, they just turn into a set of yaml files with as much or more complexity as the thing they are trying to replace. Configuration with intelligence that allows arbitrary overrides of any of the underlying configuration is important in order to meet all use cases. Without that, helm will only be useful for a strict subset of use cases and eventually you will outgrow the chart, or the chart will grow in complexity until its worthless.
