* immutability. The contents are not used within the config itself; do not confuse this with config
* user-defined properties. The properties are stored as a JSON file within the configSet that we
* read into a NamedList. It's optional; there is no file if there are no properties. Note that this
* logic is also used to load configSet flags; see {@link ConfigSetService}.
